GReddy Profec B Spec2 Boost Controller [tunning]

[boost3]

I just installed my boost controller have.I have wasted almost a whole tank of gas trying to tune this thing.Its a pita.I get it to hold 15.6 psi in the first 3 gears then after that it spikes to 21 then boost cut.I duno how do i get it to stop the spiking.Any one have any numbers?

you have to tune it in 4th gear

it sucks because no matter what, you wont get what you want in 1-3 and not overboost in 4-6...
