Hi am planning on getting a stage 2 remap from panache tuning on Merseyside my car has been mapped before not by me I have an old printout showing 278 bhp I believe it was done by dreamscience about 5 years ago it has had a de cat and induction kit but has standard intercooler I had it on dyno and it was doing 252 panache claim to be able to achieve up to 290 bhp is this possible with stock intercooler any thoughts would be greatly appreciated
