To the tuners out there.What would be the safest PSI to run on a fully built setup with 93oct?The car was put down 352whp @15psi on a MD and the tuner did not want to take it any higher.The A/F was around 11.5 and 16 degrees timing.The car has 10K miles on it since build as it is a daily driver.Thanks for any help
