can someone tell me what the maximum boost pressure is that you can run on a stock 5th gen lude?

I wouldn't suggest over 6psi, unless you have an intercooler then 7psi.

thanks

? You can go more than that. Do you mean stock internaled, or stock STOCK as in damn, you don't even have a shift **** and the window sticker is still on kinda stock?

With fuel upgrades, and some boost controllers etc etc, I'd think you could run at least 10 lbs carefully at the track.
