Thread: How much Vac

no, you can run over it for sure, but youll have to tune around the computer not being able to read that it is higher than that. i havent really heard of anyone running a 3 bar map because honestly you shouldnt be running over like 13 psi anyway. if you dont have enough flow mods for it to stay that low then youre probably knocking or running a crappy tune.

Reason being is because I had had touched 15 or 16 on a cold day with the 3.1" last winter...got a cam and headers...no restrictions in the exhaust...I am just thinking since it was so cold outside but idk...
