As above i currently have a Stage 1 VRS. Im wanting abit more power mainly mid range but not sure if i want to go the exhaust root.

So what do people recommend?

Petrol id presume. Also what remap do you have?

If you after midrange but without the exhaust, i say fit an intake such as evoms, ITG maxogen or forge twintake, then fit an uprated fuel pump. you need to get your remap tweaked to utilise the extra capability of the uprated fuel pump though (almost like a stage 1+ remap) . This will give you pretty much the same power as a stage 2 but without the extra cost of a £1100 exhaust system and no noise issues

Can i gain any extra power/torque by fitting the hpfp first. Im being fussy as i dont want any noticable physical mods.

im already suffering fuel cuts in high rpms around 140mph onwards car surges abit.

if yor getting fuel cut on a stage 1 map, your tuner is crap. Very rare that you hear of fuel cuts nowadays, only when the tuners were new to the cars and didnt know of their limitations. Fuel cut happens at the mid range though not high RPM. what your probably getting sounds like boost surges at high RPM, which IMO would be another sign of a crap map or something broken on the car

Do you have a VCDS or live anywhere near someone with the VCDS . DO some logging of your car. Use this website as a list of what to log. Very good list of blocks to log.upi your results then some of us can tell you if what your running is normal for a stage 1 as theres lots of us with logs of our own cars

reference any power gains with just a stage 1 map, it all depends on what rail pressure you map is requesting/and or making. If its high and the car is struggling to make requested rail pressure then you will see gains. IF its not high, anf its not struggling, you wil need a software tweak

I will do some measuring tonight. What do you recommend i measure?

i posted a link in the post above. Click where it says website in post #2

It doesnt happen midrange. Only high rpms at high speeds

So should i log all of what the items they recommend?

So should i log all of what the items they recommend?

i would. mainly as it will highlight a problem if you see one. Also its good to have logs available to look back at in the future if you develop an issue with the car

Thanks will do this tonight then

Many Autobahns in Oxford???

Loads mate lol! But back to the point, whats peoples opinions on the nuespeed p-flow kit? I did log and it seems my air flow is at.190g/s I have a feeling the heat is making ecu pull timing back. So what do you guys think?

this was my PM reply after looking at the logs

Had a look mate. Your boost seems around what is expected. You definitely dont have fuel cut as you r making more than the requested rail pressure throughout. Also as its only requesting 109.99bar @ you will not see any gain by installing the uprated HPFP.

The uprated fuel pumps can handle 130bar which gives a huge mid range increase.

However you have alot of timing pull. Its widely accepted that the highest acceptable timing pull on the TFSI is around -5^o. ideally your car should have 0^otiming pull. This means the car is pulling back @ high RPM due to knock on the engine. This could be a result of your inlet air temps being to high, exhaust gas temperatures being to high amongst other things.

What grade of fuel are you using. Remaps often advance the timing to make extra torque/power. However to allow this they need 98-100 ron fuel otherwise the car will need to retard the timing to allow for the lower grade fuel.

It would be handy to see what your requested and actual lambda logs, as well as you intake air temperatures. This might point towards an issue with the map or car.

Also your Mass air flow can also ellude to what your rough horse power is.

The tuners all say and work off the factor of the MAF value, divided by 0.81= the rough Hp @ any point.

your Peak Mass air flow (MAF) is 190g/s. So your making the power as that would equate to around 234Hp. However with the current external ambient temps you could expect that reading to be somewhat higher due to due to cold air being denser.

my car at stage 1 with no other mods made 203g/s which equals around 245-250hp and that was logged in the summer with an ambient temp of about 25degrees.

for your information When you log you intake air temperatures, which i highly recommend you do as it highlights how poor the standard intercooler is, you will see your temps raise by around 30degrees and take ages to recover to the ambient temp. bear in mind that for every 1^o the inlet temps raise, you lose 1Hp. This is called heat soak. So from the above if your inlet temps raise by 30 degrees after a big power run, yo

uwill lose around 30hp until your intercooler recovers and cools the inlet charge down

As i said in the quote above, you need to log your lambda, MAF and IAT blocks. That will answer your questions.

Neuspeed powerflow is not a bad Intake at all. Not the top end but id imagine it'll give 90% of the gains the top intakes do.

I have got the Neuspeed on mine and it was making a max of 158g/s on the standard map. I need to pull my finger out and get some logs now that it has a Jabba map on it.

I have modified the intake slightly with some insulation and also fitted a heatshield below the intake.

Il log in a bit mate. and pm you results

no worries pal

Donovan, if your still after a Neuspeed check this out.

I can confirm this but in my defence the Shell garage never had any Vpower left
