Hi I currently finished tuning my 2001 buick regal gs at 10psi with the cartuning turbo set up and have a manual boost controller I can hook up. Was just wondering if I could safely up the boost more. I have plenty of fuel and zero knock across the board on 10 psi at 17* timing. The kit comes set factory at 10 psi but I am wondering how much more boost i can run. Everything is stock in the engine other then 42.5lb injectors. But the engine internally is completely untouched with 72,000 miles. I heard over 10 psi we get valve float. Would just like some one to confirm on this.
