I'll second Steve's comments regarding the APR Pump. We both owned AT pumps which performed perfectly however I think we were extremely lucky to have had some of the very early ones. The later ones appear to have suffered in the quality department from what I hear. If I were buying now it would be APR.

My top five mods for the MkII Octy vRS from personal experience in order of 'effectiveness' and bang for buck would be:

1. REVO remap - a real nocticable improvement in performace and drivability, it's what the car should be from the factory imo.

2. KONI FSD's - fantastic value for money and perfect for improving road holding/cornering abilty without jarring your spine.

3. Uprated Fuel Pump - improves mid range punch immensely, ironing out any issues with fuel cut (must be done in conjunction with Stage II+ to get the best out of it imo)

4. EVOMS - not a huge increase in power (maybe 7-8bhp over a standard OEM panel filter) but improves power delivery and audible pleasure.

5. tbh I cant really think of what I'd put in fifth position as all the other mods I did made very little impact ................. I'm not saying that there was no benefit in adding the other components only that their effectiveness was far less noticable.

TBE exhaust and possibly Eibach springs would need to feature in there somewhere I think.

erm no, not from my perspective at least

You've changed.

I found the DP and sports cat to be surprisingly good.

I installed my BF stage 2 software without it and while it felt more torquey, it wasnt any different up top. When i did this upgrade the power really opened up and even when I ran the car on the standard map with the CAI and DP/Cat it seemed to dive a lot better.

For me it was a must have item or else the stage 2 wouldnt work right.

Hof,

If you managed to do most of the other mods yourself then fitting the pump for you will be easy. Checking the cam follower is even easier. I managed to do both and i have no Mechanical know how whatsoever. As long as you set TDC then you will be fine. You will then be surprised by the results. I was and im only on Stage 2 not stage 2+

LOL you bugger....egging me on

Its tempting and as far as I know the stage 2+ bluefin map is also free (need to confirm that though).

I'm not too worried about the fuel pump work, more just the inconvenience of it all.

Also as the guys are saying that the autotech internals can be dodgy, that's a concern, the APR pump just isnt good value, £700 inc VAT....thats nearly what I've spent so far :eek:

Are there any other decent/cost effective alternatives?

Using a 0-60 calculator based on a kerb weight of 1400kg its estimated at about 260bhp.....not sure how accurate these calculators are though.

The AT internals have had some quality issues as of late as mentioned earlier. TBH the APR pump although expensive is prob the better option and (i would imagine but as i said earlier im no mechanic) a damn site easier to fit as it should be just a straight swap ( i know it wont be that straight forward) but wont mean stripping a pump apart.

As for decent alternatives. TBH when it comes to messing with parts like that (i.e which could go bang with bad results) id rather pay for it. I am considering the pump myself so if i do get it soon ill sell you my OEM pump with AT internals (early batch so no issues) as i dont intend to get rid of my car it's become my project now

My point is that the fuel pump upgrade is a very good way of upping performance and drivability and is right up there with the best modifications on the TFSi you can do. My only caveat to this is that if I were about to do the same thing now I'd save up the extra and buy the APR pump, not only does this have the uprated internals but other 'safety' factors built in to the pump design that the OEM version does not have (have a word with Keith at JKM about this, he has had a lot of experience with all types of fuel pump upgrades).

Have to agree with you on the FP Steve, essential upgrade....

Great stuff, let me know if you come to sell it.

Start performance are doing a same day fitting service, you post out your pump to them, they fit the AT internals and return it same day for £299+Vat.

That way you dont have to muck about with the rebuild, I would attempt it if i had a workshop but I dont fancy doing that job on the Kitchen counter (wife would kill me!)

Hardly a rebuild. Its a case of remove pump, remove old internals, place in new, reconnect pump, rid the system of air by opening drivers door 3 or 4 times and job done. Took me 5 hrs iirc to do it but i was being over cautious. Could easily do it in 2

for those interested in or had problems with bluefin stage 2 or 2 plus

below is the results and experience of a guy from a mk5 gti forum

Well,

After the milly, Forge DV and the carbonio I was suffering boost spikes which in turn led to fuel cuts on Bluefin Stage 2. I had SC modify the boost request in the mapping to control spool-up and smooth the spikes which solved the fuel cut issue (which is basically what Revo are doing with the select settings some of you guys run).

Today, I was at AmD in essex with the car and did a bit of diagnosis, testing and replacing

To prepare Superchips supplied me with 3 maps to install :

My specially modified Stage 2 map :

I re-installed this map at 05:00 this morning after trying my old stage 1 map again over the weekend (stage 1 Bluefin on a hardware modified car does not work - especially if you've fitted a downpipe and race cat - the lack of a pre-cat really reduces backpressure and subsequently allows the car to develop more boost than the stock stage 1 bluefin maps knows what to do with.) and drove from my place in NL to Essex UK via the EuroTunnel. So the map was well adapted.

First run on their dyno resulted in the following peak measurements : 260.8 HP @ 5422 RPM and 281 lb/ft at 3487 RPM - pretty much what a stage 2 map with a milly should do on a normal GTI. But as you can see from the Dyno graph, the flat spots I was complaining about are quite clear.

After having a good diagnostics going over on the car, AmD checked the cam, and cam follower on my fuel pump, removed the fuel pump and fitted the uprated Autotech HPFP internals.

After testing the car, using the same BF map as the first run, they did a dyno run to show the effect that the uprated fuel pump alone had on the running of the car.

The resultant peak measurement was 267.5HP @ 5413 RPM and 304.9 lb/ft @ 3492 RPM - now the car could fuel for the boost being requested and as a result the ECU could adapt timing etc to be 'happier'.

Now the other software: SC provided a fall back HPFP adaptation of the normal stage 2 map that would work if all went wrong and a specially developed more aggressive Stage 2 + map specifically for cars running with an uprated HPFP. We decided to install the stage 2 + map for the uprated HPFP. After adaptation, AmD did a dyno run :

This time with effect of the SC Stage 2+ map and the HPFP the resultant peak was : 274.2HP @ 5431 RPM and 310.8 lb/ft @ 3492 RPM.

The biggest difference though is the shape of the torque curve : it really filled out and was much flatter than before. Comparing what I had and the result shows a 40lb/ft of torque delta from around 3200rpm to around 4500 rpm.

The result : me a happy chappy, the car driving extremely well and with no hint of fuel cut or flat spot, just a solid linear surge of power.

BIG BIG thanks to Superchips, Michael Alvey-Anderson and AmD in Essex, Sean and his team.

Here are the graphs :

All these runs were done with the following fitted to my car :

Normal 2007 GTI 2.0. TFSI (BDA)

Milltek Hiflow Downpipe

Milltek HiFlow Cat

Milltek Resonated Exhaust

Carbonio intake

ITG Panel filter

Forge DV

and then for run 1 : Customised SC Bluefin stage 2 map

and then for run 2 : Customised SC Bluefin stage 2 map + Autotech uprated High Pressure Fuel Pump

and then ror run 3 : SC Bluefin Stage 2 (+) map + Autotech uprated High Pressure Fuel Pump

revo stage 2+ sees 288bhp 345Ibft torque with all mods including intake and intercooler,

so very potentially you could get the superchips one to near that as the guy above is only running the carbonio which is essentially a panel filter with a ram air duct, and std intercooler

. i would be interested to see a revo stage 2+ torque curve along side the bluefin stg 2+ curve to see how close it can get to repicating the revo map, as revo is pretty much the bench mark.

I also think that shows good customer service there, in trying to sort out the issue.

very nice but all stops at 5500?? cant you go all the way

good power gains you have there sir must be a blast to drive:D

not my car mate as it says above theat post. but it will be in a few weeks.

id just been researching about over boost issues relating to the bluefin, and this guy luckily had provided all the gunei pig info, so i can enjoy it with out any side effects. I hope!

The graph seems a little peaky, dies very quickly after 5500 rpm. I'd say the problem is with the higher boost etc heat may be the problem which an extra FMIC like a twintercooler or similiar could help. After seeing makefishes car with revo stage 2+ reviews the graphs compared to above and driveability will be hard matched. IMO i'd go for Revo over SC.
