This is the dynograph from my last visit at the dyno. Im pretty impressed. These are STD #'s on the chart below, not SAE. SAE is 473/495

MAX 494whp 518TQ STD

All 3 of these runs were done in a 5 minutes period, notice the dropoff in #'s

air fuel for the 2nd pull

Its whack and a tad lean, it hasnt detonated yet or pinged. I dont like it though, although IF I can get the 12.6 accross the range, I know these cars run lean in the midrange, but oh well.

Impressive numbers....except for the A/F. I wonder what is keeping it so "whacked"? I guess I would be concerned too. I was trying to remember what changes you were going to check out on the dyno. The "X" pipe? Anyway, good to see that you are still working at it. :D

Broke7,
Those are some very impressive numbers but you have a very serious air-fuel situation with the boost you are making.Either your chip is not making good contact with your computer or your dyno air-fuel filter needs changed for more accurate results.Most chips from any tuner will start adding alot of fuel around 3000rpms to a safe area than leveling off with a pullied car and yours does not come into until after 5000rpms which that type of air-fuel graph you have it looks like with a non-chipped pullied car.Your air-fuel should be at least in the 12's between 3000-4000rpms and leveling from there.

Yeah Allan I would say its gotta be something in the A/F equipment, dont think the car would have been together this long with that A/F the way you beat on it!

Im surprised your seeing as much low end torque as you are with the A/F being so lean at low RPM.

Holy Torque Batman!!!

Those are really good numbers for a car with as little mods as yours. I dont know how you can drive her around with an A/F like that, I'd be scared to death.
