Greddy Profec B- Spec II Help

Good Boost Control? Bad Boost Control? People say it can't hold boost.

Mine isnt holding boost. Does anyone have it too?? Can someone please tell me the settings which I should set it at for 20 psi?? I have K&N INtake and Greddy TT + BOV. And people talk about plugs. There are 3 on the valve unit. Are all those supposed to be gone and is the air filter have to be on for the control unit??

it can hold boost, people dont know how to tune it. It took me a while to tune my.

if you "dont" hold boost, if it goes from 1.3<1.1>1.3<1.1 then you need to adjust the gain lower it a little. Do a run, it should get better, then lower it a little bit more until it gets a good steady boost hold.

if you have it installed i can help you tune it at the meet. If you need a boost controller i have them in stock =)

let me know if you have any other questions
