Hello and merry Christmas , well I got my 2006 apex running pretty good now I installed a bigger fuel pump ,bigger injectors 570 i beleive they are ,head shim dyna jet programmer with a map for 12 pounds of boost runs way better now my question is that the aft readings are 12 to 13 at wide open throttle is that safe on pump gas ? I don't want to blow it up again I am from saskatchewan so a flat lander I was having problems with it hitting the rev limiter before ,I also noticed the boost gauge would spike to 20 pounds of boost then level off back to around 12 ,I took the clutch off my stock apex and put it on there and it pulls way harder now and the boost don't spike like it was do some clutching now to it hopefully all is good what a rush to drive with 12 pounds of boost wow

I was always told wot on pump gas 11.6-11.8 to be safe. 12.5 is great power but doesn't last long.
