Help me with this guy Theres a guy on a local forum that is saying something about he can switch between high and low boost on an 03 Cobra. I didnt think you could with out takeing a pulley off. Does he know what hes talking about? Below is his quotes along with my responses. BTW his last car was a SRT4.
Whats done to it that you need a tune already? And its blown changing between "low boost" and "high boost" would be changing the pulley between larger and smaller sizes.
That is all I said so far.
I need to have it tuned though. Running low boost 14psi.. I have a new car though. No more blue srt-4.
No its silver! And yes she is blown but not tuned. Running low boost too. She dont' get tuned till mid may. Just want to see what she does pre-tune and get some seat time practicing launches without breaking a halfshaft.
Not stock blower you can change boost from 14psi-21psi of course 21psi would be for a fully built engine.. I am hoping the tuner can safley up the boost to 17psi most people are running perfect on 17psi
That is all I said so far.

I know you can use some BOV's to prevent an over boost, not sure if you can use a superchargers bypass valve in the same way, but I don't see why not. But that would mean he would always have the higher boost pully on and the bypass would vent the extra psi to atmosphere.
