ok so i bought and ek with gsr swap. It has some nice bolt-ons. well the car still had the d16 p2p ecu in the car....i recently got the p72 that matched my motor, but im having a little lag around 2k rpms. From take off, it will go, then lag at 2k, then immediately speed back up...any reason for that?

 

mine does that as well

 

do you think that can hurt anything? i have been driving it like a grandma
