Hello,
I have my car running pretty good but the WOT is way rich on the wide band, 11:0. Just want to make sure I steer the tuner to the correct table to lean out WOT. Do I just have him increase the values in the "Power Enrichment vs. RPM"?? Thanks

 

this should help

I have to ask. How did the dyno session turn out? Any numbers before and after?

 

Made 336 RWHP and 360 RWTQ, that was with 31* timing and the AFR at 11.5 at WOT. Any more timing or leaning it out it would ping. I was running 93 octane but its 11:1 compression. It wants higher octane if I lean it or add timing, so thats all im getting on pump gas. Kinda sucks being it made 467HP and 517 TQ at the flywheel.

 

Pretty nice numbers for a third gen. I like the Grand Sport stripes, where did you get them? And is that paint the U80 GM paint code, Monterrey Red?

 

What rpm did you peak?

 

I saw U83 in center console

 

Peak HP was at 5500RPMs..

 

That's sounds about right, I was hoping to get mine to peak at 5500,but with a smaller cam (228/228), not sure if that's going to happen.
. How does it pull on the street?
Get some high octane in there, see what she does with less fuel and more timing. I think you have a lot of hidden horsepower in there!

Anything else causing detonation, hot plugs, bad egr. How do the plugs read?

 

Plugs look good and egr is bypassed, just think its the 11:0 compression. I have another tune we made yesterday at 35* and 12.2 AFR. I'll have to try that one with 100 octane, because it was pinging on 93. The 31*,11.5 wot afr tune with 93 octane that made 336/360 feels good. Comes out of the hole hard with the 3000 stall and Mickey Thompson drag radials.

 

I bet if you run her at the strip and get those numbers you will be quite a bit happier. The stall dosn't do much to help the dyno but works wonders on the strip
