I've got a 2012 Insignia CDTi BiTurbo. So 195ps. I keep seeing more and more adverts for remaps. Most offer the same, 195 > 240ps, 400 > 480nm, extra 10 - 20% mpg.

Are these worth it? £300. Would I actually get that 10% more economy? Currently getting about 44mpg on my day to day drive. Do these shorten the life of the engine?

Cheers all in advance
 
Thinking about getting my Golf GTI done and this time leaning towards a DTUK tuning box. I have always had remaps previously but all the VW/Audi and Vauxhall owners that have had one rave about them.
 
It's early morning so I've probably got this wrong but you'd need to do 30,000 miles to get your money back with 10%+ mpg.

Don't look at it as a money saving exercise.
 
No not money saving. But better all round. More power and econmey for £300 instead of changing the whole car. My car's done 41000 miles, and i'll be keeping it until it hits 100k (life time/100k warranty)

But don't want to do it if it damages the car.

Also I saw the DTUK one. 245ps 495nm 10% on average more mpg 5% more top speed. £339

In that case I'd say go for it. Seems to be a fairly common thing to do nowadays. My dad had his E class merc mapped, only kept it for around 10k miles though and didn't have any problems.

Surely a remap voids the warranty?

Edit: thewanted - Beat me too it!
 
I've never understood remapping. What get the negative effect of remapping if there are only gains to be had and why don't the manufacturers do this remap if there are only positives?
 
Yes, but most of these boxes are removeable at time of service etc. So no one would know it has been used. While not the most honest thing in the world it doesn't seem that bad. . .
 
IAmATeaf the remap companies list a ton of reasons why the manufacturers don't do this. Its to do with restrictions in different counties. So they make a more generic ecu mapping for their car's

Got Shark Performance one on mine, fitted anti lift kit as well which makes the front end much more planted under power.

Because of reliability + extra wear it can have on the engine?

Sure, most stage 1 remaps are probably fine on a stock car. But any more than that and you will probably need to look at new clutch, fuel pump etc.

I have thought about it myself, but really can't be bothered with the hassle 'if' something happened and I'd rather have the warranty.
 
As someone who has had a turbo char remapped I can say you'll probably end up saving £0.00 over the life of the car. I was probably able to get slightly better MPG when driving like a complete eco-nutter. The difference in performance was well worth the price though.
 
I have remapped mine. The fuel economy hasn't changed but the extra horsepower is nice.

I would remap a turbocharged engine only if I was sure that the drivetrain (engine components, gearbox, clutch) could handle it.

This isn't actually true, the dealer will be able to see that the ECU MD5 has been altered and will know something has been done, they just won't know what.

Either way there's the chance they will deny your engine and drivetrain (more power = more stress than originally intended etc)

The ECU's checksum won't be altered by a tuning box because the box intercepts the signals before they're sent to the ECU. The ECU's code is unaltered, although nobody can be sure that the manufacturer isn't logging boost pressure, overfuelling etc.

EU emission regulations and other legislation they have to conform to generally mean a crippled map on standard cars.

A good remap is worth every penny.

There is no negative to re-mapping ...especially for Turbo Diesels! ;)

So you don't think that asking an engine to produce say another 25% more power might impact upon the drivetrain longevity, e.g. clutch, diff, bearings etc?

Go on, tell me that again.
 
I've read about these DTUK boxes and must admit have been rather tempted.

Finglonga have you got any links to VW reviews from owners who have used them?

I'm rather sceptical of it 'saving me money with better MPG' but the extra power would be nice
