I kow this has been discussed ad-infinitum however some of the threads are relatively old now (2005) and there may well have been new products on the market in the meantime.
My question is which ECU mapping would you recommend for me (including address and approx cost if possible) and what would be the approx range of BHP improvement be?
For your information i have converted my exhaust to quad, changed my wheels to 18" and put body kit (front Breyton rear original M5).
Will post pictures in next couple of weeks as M5 rear spoiler is arriving from Germany to PML only at the end of this week and they need 4 days to do the modifications. Apparantly this is the first time they have tried putting a M5 bumper on a non M5 car (not the M-aero kit).
