The car has been retrofitted with dual 3" CAI's, cats have been removed (O2 sensors in place) I run a mixture of 91 pump gas with a % of Toluene and Xylene and a % of Klotz Coxoc. The chip was flashed with a PowerChip Gold 93.
The car seems to be running very lean with a sporadic misfire at idle. Plugs are changed after 3 events.
So, you can see why I need mapping and alteration capabilities.
