Could be running rich after the header install, costing some HP. A guy here installed and lost 15hp on the dyno from running rich. After the tune he picked up 22 or something like that over the baseline. So there was a 37hp diff between tuned and untuned simply because of running rich from the headers

Did you gain any mph hour at the track. Thats a good way to tell if you gained any power. It couldve just been you had a slower 60ft. because of spinning. What were your 60ft times on both runs.

i gained about .3 in the 1/4, and 3 mph after my LTs, ORY, Hooker catback and cutout install, but I got my fully dyno tuned as well. A tune is a must.

He had a slower trap speed as well.
Although at our track....DA varies a TON!
I know he was back down at Bandimere today. Best day to race in the last couple weeks. Fairly cool today.

Mitch...anything to report??
