That's a coincidence. Literally today I had my water pump and cam belt replaced 6 months earlier than manufacture recommended. My engine started to overheat, even on a 5 mile journey. Water pump had gone. £489 later all is good agian. As the water pump works the turbo I have to ask is the dtuk box something to do with it? I did ask for the software to be checked as it had the usual starting problem and there was an update. Hopefully from tomorrow starting won't be an issue. But to be honest my average mpg went from 57mpg before the dtuk box to 65pmg on a long run. But it has cost me £489 for the privilege 10 months later. I have removed the box for now as it's getting cold and no extra power needed. Now got all 4 wheels on michelin cross climate ( expensive week) Hopefully a hassle free winter

So after having the box fitted for 10 days to make sure I was happy with it I had the dreaded job of updating my insurance company Admiral. After reading some reviews on other chats I was expecting a fairly big increase. My insurance is due for renewal in 3 weeks anyway. It appears admiral classify it as being re chipped and gave me 3 options for the power increase 0 to 10%, 11 to 25 % OR 26% +. Not being able to put it on a rolling road I opted for the middle guessing the bhp won't have increased more than 45bhp. Shock and horror my premium increased, By a whole £12 a year!! And that's with a speed awareness course declared from 3 years ago. So hats off to admiral (excuse the pun ) for not taking the mickey.

I've just got back from a 300+ mile journey and have to say I had no problems and no warning lights. It had power where needed although on the cold roads I did experience wheel slip in 3rd gear. Sticking to 70 mph + I achieved average of 61mpg. Mainly motorway but had some town and country driving as well. Taking into account I had the heater on, phone on charge, headlights on all day and at points both the heated front and rear screen on. Impressive. I'm going to stick to 2 +1 It works for me. Going to update my insurance company tomorrow with the upgrade :((

That's strange it's just added a comment I posted ages ago

I've had it on 2+1 since I installed it 10 days ago and I've been giving it some welly and so far no warning lights at all. It's my first long journey tomorrow 130 miles to Portsmouth so that should highlight any issues. Infact I did have the typical diesel starting problem where it wouldn't start straight away but since installing the box it starts first time every time. Wow, my final day of peace is here, although rain is forecast I'm betting on an hour of dryness tomorrow. I think from your comments I'll start with a map 2. 0 setting then work from there. Map 2 seems the best choice for mk3 Octavia diesel.

That's all the instructions say. So I fitted the CRD3 yesterday took it for a quick spin on map 2 +0 and did not notice any change in performance at all. However today I've been driving on 2+1. Now I notice the difference, admittedly I was driving harder than normal and got a lot of wheel slip in gear 1 & 2 as expected but from 3rd upwards there is a massive performance increase, thumbs up so far I'll try the others maps over the week and find the best for me.

Warning lights not what you want. To be honest I'm not a massive petrol head all I'm hoping to achieve is more power to make the car a bit more fun. The basic setting will probably be ok for what I want ( I should have bought the instructions with me on holiday so I could read up on the different maps)

How was the blast to Cardiff?

It arrived on Friday but I'm away on holiday this week so havnt fitted it yet. Monday will be the day of reckoning!! Cant wait, pick the wifes new polo 1.8 Gti up on the sunday then give my car it's little tweak, can't let my wife have a faster car than me

Thanks for all your help guys, I've just spoken to dtuk and ordered the CRD3. They were kind enough to give me a £30 discount so paid £369 inc delivery which I'm happy with. Should arrive tomorrow but I won't have time to fit it for about 10 days. I'll let you know how I get on with it

I have looked at eBay but you don't get any warranty and you never know how carefully it has been removed or it's it's been played with. I might give them a call to see if they have any online discount codes

I'm warming to the plug and play box and the CRD3+ from what I can see is as good as any other box. Does anyone know of any discount codes for dtuk? Or if they do black friday deals

Looking into plug and play boxes opens a new can of worms, so much more research to do!! And now a pedal box what on earth is one of those? As a none technical person that just wants a bit if fun, it seems a better option to give my car to a garage and collect the beast a few hours later, I'm not sure I would trust myself to set the programmes correctly

I've noticed the same I think some advertise the actual bhp increase compared to the potential increase. I'm betting on a increase to 220 bhp, 230 sounds too optimistic. All companies only offer a stage 1 remap on diesels, stage 2 are only available on the petrol models.
