yeah, downpipe, High Flow Cat/Decat, Cat back system would be good, FMIC certainly helps alot but not essential for a remap..
i had mine mapped at star earlier this year, at the time i was running a cat back system, forge 007 and BMC CDA. i dont have a rolling road printout for the car since it was mapped but i should have some figure shortly.. Jim @ Star reckons it should be about ~190bhp and ~240ft.lb from past experience, he does have rolling road facilities there but i didn't have time to wait for a power Run to be done..
Feels like a totally different car to drive, with the addition of a laguna FMIC on mine i waved cheerio to subaru impreza wrx the other day!
Well worth the cudos!
