which cars gain the most when remapped?
Discussion
Typically at best you're looking at 20% for a turbo petrol or maybe a bit more for a turbo diesel.
If you want stuff that is more than that in percentage terms it's usually stuff where either the exact same engine is offered in several states of tune and you're remapping the lowest state of tune.
In terms of sheer BHP added then it's usually an engine that is very powerful anyway so that 20% gain works out to a ridiculous figure. I know stuff like the current S6 4.0TFSI gets a pretty big headline figure when remapped.
VW engines tend to show pretty big gains too because VW love under rating them. The Golf Mk7 GTI, if you compare VWs given figure to what it dynos at after a remap is pretty big, but the figure it dynos at before a remap vs the after figure is less of a difference.

Saab 95 2.0t. Goes from 150hp to 225hp/340NM with a stage 1 remap. Add an exhaust down pipe and it will go to 300hp.
Bloody hell that's impressive! At what point do you have to start thinking about clutches / gearboxes etc?Edited by wormus on Saturday 21st November 08:38

I have read that certain BMW's share the same hardware but leave the factory with different levels of tune.
So a 325i can be mapped as a 328i and therefore go from 185bhp to 285bhp very easily.
Are there any other examples of this kind of thing?

Performance Torque posted this on their Facebook page.
"BMW F30 320i custom mapped from 179hp to 283hp. We also offer a 245hp upgrade option for customers wanting to match the higher power 328i factory version. "

225hp is fine and best part is the mid-range which makes overtaking diesel Audis fun. 300hp is about the limit of the pistons. Earlier engines were more robust and almost 500hp could be made on stock internals. Not bad for a 2.0 L 4-pot! https://www.youtube.com/watch?v=qW-z__-OcOwTyler Durden said:

Merc 220cdi are identical to the 250cdi apart from the map so 170->260bhp is possible. As far as I can tell anyway.
