after installing greddy turbo kit.......at low rpm i can feel power but at high rpm i start to feel like theres no power..........what can that be......is it my iab not working....no opening.......help.......or is that normal for turbo car.......i have the greddy blue box hook up only........

 

iam going to tune my car with a p06 ecu chip to p28.....the tuner is going to use crome to tune it.....then he will chip me a chip for that ecu....is that good or bad.......

 

greddy blue box tunes afr only. it doesnt have any real " tuning" capabilities at all. your car probibally just needs a little timing . your tuner should be able to get you taken care of with no problem.
