You will get the power, it is capable of flowing 400hp, but the drive of the car will change, don't expect a broad powerband, it's going to be like nothing, nothing and nothing then bang at 'bout 5500rpm on the 4E and all hell will break loose. Good for drag, but for daily/street driving = no good. This is because the exhaust housing and turbine wheel (i think?) is bigger on the 22 compared to the 28. When are you reaching boost on the 28?

Definitely not full boost, it's pretty laggy - starts to produce boost from 3.5k, boost is all in just after 5k
