Steps25

I ran the Dyno with only 1500 miles because I'm putting on Steeda parts, with a Diablo Predator tune and I want to see the gains.

Stock '05 GT w/ 1500 miles (put on some more miles & these numbers should go up)

RWHP= 267.9
RWTQ= 287.6


My Air/fuel is way off though. Its running sooooooo rich. Not sure if Ford sets it rich from the factory to be extra safe, but the graph for Air/Fuel plummets like a cliff at 2500-3500 rpm, then from 3500 RPM up I'm off the Dyno chart. The graph only goes down to 10 and I'm runnning 10 all the way to redline.....RICH. Could be the Dyno Jet sensor Isuppose too. I could try another Dyno

Anyone have Dyno experience???? I drop from 14.5 to 10. I hear 12-13 is good??

I just installed Steeda CAI and Predator tune but have not been back to the Dyno.
Still I'd like to be able to store a stock tune with correct A/F. The predator can lean out the car by 15% which supposedly equates to 1 point on the Dyno. Anyone with knowledge of this or how I should approach adjusting parameters.
