i have a brand new greddy profec B spec 2 digital boost controller i would like to sell. no use for me since i have a switchable tune. asking 320. they originally are around 400

 

bump

 

These are only good for a handful of cars I think (mainly older ones I think).

Good price, but I dont think you can use these on cobalts?

My buddies skyline has something similar, and somehow the car just "works" when you move the psi from 7 to 14... I think in a cobalt if you change the PSI at all, you require a complete rutune..

Me confused

 

I think you basically tune for the highest psi that you want to run, but then when you lower the boost this just causes you to run rich. Not 100% sure tho.

 

actually i had one on my car and i sold it to another cobalt owner. Only thing is they are confusing for the nuber, it took me some time to understnd it.

 

should have a solenoid with it that changes the boost when you change it on the interface it's universal

 

yeah itll have the solonoid and some other stuff including the actual boost controller
