I'm hitting the Dyno in 2 days (this Saturday). Got a 9:30am slot, so hopefully the temps will be better than last time. I've been running on that last tune you sent me for a couple of months now, so I'm sure the ECU may have tweaked whatever you left for it to tweak (that adaptive learning stuff). I'm hoping to at least get over 310rwhp, but I hope you are closer!! This will be on a new DynoJet jet. I'll let y'all know!!

Well, the new #s are pretty much the same as last time around.
300.5rwhp/ 314rwtq
A/F was STILL at 11.5:1 measured w/ the tailpipe sniffer.
Looks like I need to lean it out some more?!?
I didn't get any datalogging in, but I'll post the dyno chart this week sometime.
One interesting point, another Stang that dyno'd the exact same as me on a different dyno a few weeks ago, made 278rwhp this time around. Hard to use that as a comparison, but nothing should have been different other than the dyno itself.....

Yea those are slightly low for what I figured you could get with your mods, but regardless try not to get so caught up in Dyno Numbers because as long as the car feels good to you and you are having fun thats all that matters.
PS- I searched for that **** shop for about an hour and when I finally showed up I got to see 1 car dyno...And it was a the blue Cougar that took home the award for lowest dyno number.

Possible to datalog next time with Livelink? A step test holding it for about 5 seconds at 1500 2000 2500 3000 would be great. Just datalog fuel trims, maf voltage, and counts? Using a sniffer will throw the readings off by a little bit. I assume you're running around 11.9-12.0. Those o2's are really tricky via sniffer... have to be warmed up, and if they get hit with tailpipe condensation it throws it off too.
Using the bung for the rear o2's would be alot better, pre-cat would be ideal.
What temperature were you running at?
I know there's more horsepower in there if we can just get that AFR right.
