i have installed this peice so far but i can not get it tuned in correctly. i have my set gain in at 111 and boost increase at 17% and my gain at 30% trying to keep the boost stable but i seem to not be able to either keep from spiking or boost raising through the RPM range. im only pushing 10psi, havent tried raising the but boost yet, just trying to keep it stable. if you guys have one of these and have gottin it down thatd be great if i could get some help. my mods are simple just K&N, 2.5 turbo-back,255lph,fpr.

Lower your gain from 111 to like 10, Raise your boost from 17 to where ever you want your boost at. Then change your set gain like 10 points less ten your boost increase. It your your boost goes right to where you want it then spikes, lower your Set gain by 2 points each time until it doesnt spike. It your boost starts to drop off at higher RPM then raise your gain by 2 points until it stops. It take a while of playing with it. Good luck

thanks, when u mean 10 on the start boost do you mean 10 psi (100 on the controller) or literally 10 on the controller itself since dialing in 10 would really be 1.0 psi ? im pretty sure u mean 10psi though, and the spiking problem i was having before was it would shoot up to lets say 15 and then settle down at 13 ( what im shooting for) is that alright? my biggest problem seems to be the boost increases through the RPM's, thanks for the help im going to go out right now and do those things.
