Nice car and combo. With some tweaks you will get it sorted out, mine took a while to get the right parts working together.
I had my car on Futral's dyno and Geoff's dyno. Both made the same power.
As I changed from Allan tuning my car to getting efi live my self and Geoff teaching me how to use it I tuned both my Nova and my Trans am at the track using an Lm1 wide band . by track tuning and tweaking , both cars went to Geoff's dyno and after several pulls on both cars never found any more power on the dyno then the first pull. I was impressed with my self and so was geoff but I still had geoff help me clean up the idle and some drivability issues.
Just shows that tuning for mph is the best bet and you can also do that by data logging on the street and looking for what makes the car excelerate faster on data logg. Not seat of the pants.
Dyno is just to impress on the INTERNET not to make the car faster.
Dyno won't load the car like the street will.
As seen earlier on here, I also set my stoich at 14.2 and like 12.5/1 wot because ofthe added ethanol in gas these days.if your using nonetheno gas only then 14.68 stoich and 12.8-13.2/1 is where good power is made.
Also I'm not big on high timing, have not seen much performance gain at the track going from a safe 27.5 deg uo to 29 of timing. Good combustion chambers dont need as much and with the compression your running it should not need it.
Just my 2 cents, Merry Christmas.

Wanted to update this thread a bit. My 1 7/8" headers will be here Wednesday, and they should be on the car by this coming weekend. A buddy of mine, and the guy who built my car, now has a dyno in his shop. I'm going to get some dyno numbers on his dyno with the 1 3/4" headers and then some after dnyo numbers with the 1 7/8" headers and some touch-up tuning. I think the bigger headers are going to net me around 15 or more RWHP. The headers I have now are 1 3/4", but also have 2.5" collectors, so going to a 1 7/8" setup with 3" collectors is going to do a lot for the combo I believe.

418 rwhp 380 rwtq. I think the torque number was so low due to the 2.5" collectors on the headers. This will not be done on the same dyno as those numbers came from, but we are going to do some pulls with the setup as is, and then some pulls after the bigger headers are installed, so it will be a true back to back comparison.
