Bad day at the dyno le2 combo results
94 camaro z28 le2 combo,30 lbs fords,255pump,58mm asm t/b,passetters,flowmaster catback,3400 edge,12bolt 3:90 gear.
A/f ratio was about 14.2 across the board,we added fuel only to see it wasnt helping,(fuel pressure was at 46psi) found out that the volts were reading low(12.5 volts) it has 14.00 volts at the battery(which is in the back) and alt,but only 12.5 volts after the pcm,we checked it at the injectors it was 12.3 volts we then tryed to boost the volts by hooking up a charger to the post and it had 13.6 volts,so we made another pull and the a/f went to 13.00
I also has 2 codes 33 and 64

What gauge wire are you running from the battery to the distribution block up front? If it's not large enough then line drop (voltage drop in the line) may be your problem. Also check your ground connections.
the wire is either 2 or 0 gauge,it made 351hp304tq when the a/f was 14.2 then when to 359hp316tq when the a/f was at 13.0
I went to the dyno a few months ago and was told I was lean with a a/f of 14.5-15.4 but it made 363hp366tq?

grounds seem good I just added another from the motor to the frame,the one on the motor mount to the battery,I thought it should be to the motor? I just tryed cranking it and the volts dropped below 11.0 until it started? It doesn't have a problem starting or holding a charge,I just started it after sitting 3 weeks.
