how much boost can I Run

[oneslobuick]

Finaly wen to the track fri and the clock was broken but i made a few passes any way. The car feels fast, Im running 19# of boost and 43psi fp line off and the car had 0 knock and o2s were in the 580 to 650 range all the way down the 1/8 mile track.

so my question is since I have no knock can i keep increacing the boost or should i just lower fp and see if it gets faster?

this is with 93octane

If you're gonna tune with the stock narrow band sensor, shoot for 780's or so

You plan on pulling fuel with the TT chip, right?

Where are you getting your O2's from? Scanmaster, Direct Scan, Powerlogger? Those O2's on pump gas with 19lbs of boost are asking for a head gasket replacement. Do you have alky? 780-800 are what most call good. 760 is lean even know I have run 740-760 on 18lbs with 110 octane with no problems.
