5.3 LM7 Dyno Results
#1
I dyno'd my pickup today at Strictly Performance (Yeah, it's a 'stang shop) to see where things stand -
. Pulls were done on a Dynojet @ 95F at about 96% humidity in Houston. Richard at Strictly Performance said I was running a little rich and could get a few more horses leaning up a little. Based on my mods and such what do you guys think?
Pulls were done in 3rd gear. I have 3:73 rear end.
I have a Comp 212/218 115 LSA Hi-Lift Cam - Patriot Gold Spring Kit - Hardened Pushrods to add this summer.

I don't believe there was any weather correction. The pulls were done in 3rd gear. The guy running the dyno commented on how hard my truck shifted even though I installed the Transgo with the softest settings. Charlie Wheatley is looking at the A/F ratios and I'll likely get retuned. Once I get that done I'll go back and redyno. When I do that I'll see if they can put RPMS on the scale instead and weather corrrect, etc.
I saw your dyno curves, you pulled more horses with just a muffler, filter and tune.
