In our continuing saga, our intrepid hero, SoundGuyDave, has won a dyno session in a car show raffle, and strapped his trusty steed to the rack... As you may recall, he was complaining about the tune feeling "flat" in the upper RPM range, just not wanting to keep pulling. No codes, no stumble, but no balls (can I say that here?) either. Enter THE DYNO!
Please note the tuning company's name has been redacted, until they have the opportunity to respond privately. Granted, this was a second gear pull (test purposes), but that should have no effect on the shape of the curve or the A/F ratio, both of which are pretty ugly.
Fortunately, our intrepid hero was prepared, with a tune he received THIS MORNING. Promptly uploaded, and in a 4th gear pull, delivered this:
The car feels a lot better, but shouldn't I be getting some higher HP and torque numbers? Mods that count are: CAI w/90MM Lightning MAF, Steeda billet deletes, Roush 25% UDP's, FRPP 3.73 gear, Nitto P285-40/ZR18 tires on Liquid Metal "Static" rims (18x9.5").
Any thoughts?
