ive got a 2010 Mitsubishi lancer gs2 di-d.

i have been thinking about going for a remap but still not 100% sure.

websites say i should be going from the stock 140 bhp to 172 and then there is the torque increase. is there likely to be a noticeable increase in performance?

places are quoting between £250 and £300. is this about average?

also if anyone can recommend a place in Glasgow. after a search on Google there are a few around but not sure who to go with.
 
I wouldn't bother, it's only going to place more strain on the drivetrain components and wear things like the clutch, DMF, injectors, etc etc out prematurely, will will end up offsetting all the fuel savings you've made.

I guess it's a different story if there are other versions of this engine available in the range with higher power outputs with otherwise identical components.
 
Do listen to the above comment
Your car won't suddenly explode after being remapped by a professional outfit but it will put increased strain on certain components especially on a turbo car where you will see decent gains

Common occurrence for a remapped car to suddenly have a slipping clutch where the original clutch is worn and an increase in torque shows the problem up
 
I remapped a Volvo S60 185bhp to 250bhp with the dpf removed clutch was fine and it had done 125,000 miles

Also someone on here remapped a T5 from 260bhp to 320bhp, again no problems

Aslong as you don't rag everyday it will be fine, If you remap a diesel and drive it normal the mpg will be better
 
It's not so much about ragging it every day, it's the norm for folk who have remaps performed to come over all 'ooh and ahh!!' about the extra torque which suddenly becomes available and then using that torque in higher gears to roll on for overtakes etc rather than changing down a gear. While this in itself is quite a satisfying aspect of having a remap performed it does indeed put extra strain on drivetrain components especially DMF's and clutch parts. The increase in outright bhp isn't the issue, most remaps especially on diesel turbo engined vehicles provide an extremely healthy dollop of extra torque which if not treated sympathetically by the driver can be the one thing which eats drivetrain parts for breakfast.

However, your mileage may vary - for every single person who says 'I wouldn't remap my car as it will kill/did kill my clutch/DMF' there is another individual who can honestly say 'Mine was fine, remapped it to xxx bhp/nm and the clutch was perfectly fine. I'd say it was 'at your own risk', just be wary of the possible consequences.
 
I've never remapped a car, nor wanted to. If I haven't got the performance I want out of my current motor I buy the one that has got what I want, as stock.

I'm a stickler for stock cars though, I am sure there are safe remaps available and are worthwhile upgrades, but for me I feel as though I’d rather be pushing the car on what the original manufacturer decided was the best combination.

If BMW have decided that the M135i is best suited to 320bhp then I’m not going to get it chipped to 380bhp. Makes my skin crawl when you hear of these stories on the 1 Series forums.
 
Nothing wrong with a remap as long as its done safely and by someone who actually understands what they're doing. Not a diesel but my scooby is remaped and it may (certainly will the way i drive it..) wear the clutch more quickly but that's a sacrifice im willing to make for the extra performance, just need to be aware of things like that.
 
Get a superchips bluefin, their maps are generally quite conservative compared to the likes of Revo etc and you can easily revert back to stock anytime or even return the unit back for a full refund if you are not happy in the first 7 days (after flashing your car).

You only live once..
