i have a 2001 prelude with a t3/t4 turbo... auto trans ... my ? is, why is it when i boost anything below 10psi the top end falls off (5000 rpm up) and above 10psi it pulls hard to redline... the car has not been dyno tuned so its runnin kinda rich... but why is it that below 10psi it falls off top end and above 10psi it pulls really hard...

 

bump

 

bc u have a T3/T4 turbo and tats a big turbo for a small car. higher boost always have higher pull, and lower well u see my point, but not sure
