this is old topic but still hot :)
did you log after putting those settings? car will feel.great, but it will not be great once you log lambda actual vs requested, lambda regulator, both boosts, maf g/s. you will have situation between 5000-6000rpm. i speaking on revo stage 3 map.
cannt speak generally for all cars, but few of them had same thing. nothing bad will happen, but lambda actual cannt meet requested at that rev range, and few other things.. and I preefer to have all parameters spot on
