Well, just installed the Racechip Ultimate. Took an hour to install, mainly due to the fact I forgot to plug one of the cables back in under the air intake other than that, so simple. Haven't had a chance to take it out for a proper drive, but so far driving normally feels the same. Once you put the foot down and hit 3500-4000 RPM, the extra power really kicks in. I'm also noticing a slight increase in noise from the intake/exhaust. Not had any issues with the car. No warning/engine lights or anything.
I really need a dyno, just for curiosity. May look into that.
Hey @Mart2912,
How has the Racechip been performing for you? Have you had a chance to dyno your Mini yet?
Do you have a copy of the installation guide that I could have a look at, please?
