Well, I have read a lot of threads on setting the Profec but I can't get mine to hold peak boost. Here are the settings I have: Set: 50%, Gain: 25%, Set Gain: .70, Warning: .83, Warning L 30%. I have tried a lot of different combonations but I can't get it to hold .80 which is where I want it. Everytime the car boosts it reaches .80~.82 and then falls off to aroud .55 or so. What setting do I need to adjust to get it to hold at peak boost. I started out with the settings from this post: https://www.rx7club.com/forum/showth...=192249&page=5 They are: for 10 psi....

37-38% duty cycle
0-2% gain
9.5 Set/start boost

Any help you all could give me would be greatly appreciated. Thanks for your time.

 

Does nobody have a Profec B that is tuned correctly?
