Took it to the track tonight and made 2 passes and done what tuning I could. On 10psi spring only the car went 7.39 @ 100 mph 2200rpm launch and 1.98 60'. 2nd pass hooked the boost controller up that made 15psi with the 6262 and adjusted it -10 clicks that would put me at 12-13psi, activated 2 step for 2800rpm and had timing advance 5* from 2500-3000rpm ( about 20* retard). Got it to stage and up on the 2 step it started popping and built 5psi rather quickly and started to push so I let it roll out red lighting. Glanced over at the boost gauge and it pegged my 20psi gauge and af was 13.5. Got some knock so let out of it.
I've got some work to do on this car over the winter. My main priority is to ditch this returnless fuel system. running 2x 255's and the pressure on the rail was 25 a couple frames. Fuel pump duty cycle was mid 80's though so there is plenty pump so something else is going on. Got to look at battery voltage to see if that's the culprit. More than likely the driver modules are going bad.
Fuel was 70/30 110/93 non ethanol pump gas. I had intentions on getting boost up to 15psi but got a head ache and didn't feel like working on the car any more tonight so called it quits for now. I'll make the switch and return the fuel this winter and try it again next spring.
