My Dyno results
 
Run #1 was on factory setting, 191.09 HP 201.79 TQ
#2 was 87 perf 180.83HP 208.72TQ
#3 was 89 perf and run 185.80HP 215.76TQ
#4 93 Tq setting 186.41HP 220.74TQ
The A/F is not optimum so that may need to be worked on if im not hurting the engine the way it is, and i was surprised by the fac stock # didn't expect it to be that high with the minor mods i have, oh well what you guys think?

I gained tq in all the perf settings, don't know if hp loss is normal though,and why the hp#'s wouldn't go up also, would like to hear from Doug or someone with some experience.
And from what i understand if the A/F was lower in the 13's i would make less power, also the temp that day was pretty hot as shown on the sheet although the humidity was low,
and another note the first run was done in 3rd gear w O/D off and it locked the tq converter, so the last 3 pulls were done in 2nd gear to prevent it from going into lockup, the concern to the operator was the speed going above the rating for the tires, it sounded awesome though :smile:

looks good. even so, you didnt get your best numbers on the tunes, you only get peak performance on the performance tunes after the computer has had a few miles and drive cycles to relearn everything. so if you flashed it just before the dyno, youre still running in a form of safe mode.

hmm, sounds like I need to set a date with Steeda to get dyno'd or tuned.

Yes thats how it was done, it wasn't logistically possible to put miles or time between each run, as there were other people waiting, thanks for the tip, next time I'll just run it in one setting i guess.

I would be interested to see what it looks like after you have a few miles on each tune first.

True. But then you'd have to factor in different days, humidities, etc. How long does it take to get out of 'safe mode' when you put a new program on?
