The other week I went to the track and set a new PB on street trim. Basically nothing but tailgate removal and headlight removed while running on 80# wheel combo (22" wheels and 31" tire). But to me it seems a little low, what do you guys think?



Mods in sig, and I'm at 104% IDC and 11.9 - 12.1AFR WOT. I have 44#'s coming this week.

Honestly, I have no idea why its running fat. It was tuned dead on 12.7 but then the truck threw some codes and its been like that.

This run was against my buddy w/his 4.8 swapped s10. Only mods is a 02 LS6 and dyno tune. Wasn't my PB run though. Sorry for the crappy sound, it was on my phone and the cut-out was off

I guess I didn't grind the calipers enough bc my 15" wheels were catching, so no runs on the slicks

 

DA was 459

 

97mph with 338rwhp in a excab sounds pretty close to me, I bet you would of been 99mph with 12.7 af.

 

Not too shabby.

 

What time of year was it tuned? I'm tuned for fixing with an Avg DA of around 4500 and run rich when I go to phoenix which has an Avg of 2500.

 

This should never change, 10 degrees to 100 degrees my ar always stays spot on with the wide band, now I have open loop speed density so it does a little.

 

I believe it was tuned in the fall, can't remember off hand.

But thanks guys!
