I've got a 94 G30 van with 5.7 TBI, 4L80E. I just put Vortec heads on it, the intake from Summit that uses TBI on Vortec heads, knock-off Doug Thorley tri-Y headers, dual exhaust with flowmaster 50 series mufflers. EGR is connected. Scorpion 1.6 ratio full roller rockers. Stock cam. Going for torque and highway mileage. Oh and I did the convert stock fuel pressure regulator to be adjustable thing and adjusted it to the highest pressure, but I haven't hooked a gauge up yet. And a 3-wire O2 sensor conversion.
So I don't start form scratch, anyone got a bin that would be good for my needs? I already know that I need to adjust the fuel enrichment parameters, since from the little bit of logging I did, it seems to run rich at idle but lean when revving.
Other than a good bin to start for this combination, what else should I look at modifying for starters?
Thanks in advance!
Oh and I borrowed power for the O2 sensor from the ignition-on hot wire to coil/distributor, and thoughts about that?
