Took the car back to the track Friday night to do some tuning after the new fuel system. Fuel curve pretty much wants to look flat as the additional pressure provided by the boost reference seems to handle the additional fuel demands at the higher KPA. It was hot and humid out and my converter was about to catch fire from hot lapping it. I ended up running a best of 10.15 @ 135 with a 1.51 60'. The car left good but the converter wass just too sloppy at 220*. It's way too loose anyways. I really need to ship it off to Greg @ FTI to get it restalled. The good news is that after spending most of the night leaning it out, I finally got it down into the 11.0-11.2:1 AFR range (still rich, I know) and the injector duty cycle is now down to 74% (from 130+%).

and your still on pump gas????? whats your WOT timing?
hurry up and get that converter tightened up, it's painful to hear that motor make power while the converter lets half of it slip away.. it wheelie's like a **** but after that it sounds like it's slipping bad

13* of timing at WOT. I think the valves are floating also. I hope to send off the converter in the next few days. I'm trying to coordinate it with my friend that does the TIG welding. We are going to move the charge pipe so that I can get the air filter routed out of the engine compartment and get a bigger filter on there with some cooler air moving across it. I would love to have the rear end done at the same time but that's wishful thinking.

i think those are the ones with a gto passenger side manifold... about 99% sure the truck manifolds can't be used with the factory a/c compressor setup, but i leave 1% for error
