Boost Drop

[reflex]

Ive had a hks 2535 on my r33 for over a year now and it hasnt missed a beat.

i have all the necessary mods to keep everything running well and peice of mind.

i have been runnign 1 bar of the actuator since i installed the new turbo and it makes a healthy 231rwkw

i was winging a few months ago that i wasnt happy with the response even though it makes 1 bar at 3000rpm. couldnt be bothered with cams or whatever so ive wound the boost up.

ive set peak boost via a bleed tap at 1.20bar. The car is now making 18psi at 3100 rpm and is awesome.

only problem is it doesnt hold 19psi, it drops to 12-13psi by redline.

ive checked all the piping and everything is fine.

Is it because my pfc is not tuned to run 1.2bar???
