Sluggish performance after first mods.
Ok, so I installed my first mods recently. First was a built 4L60E w/ a 3500 stall capable of 700 rwhp. Second was race pacesetters (!AIR, !EGR, !rear o2's) complete with True duals dumped at the axle. I took it to the track and got a terrible time of 16.6 E.T. WTF! Where should I be with these mods? My gears are stock 3.23. Could that be a factor? Also, when I foot brake at the line the rpm's stay at 2500. This is with the pedal to the floor, is that normal? The car launches like crap. How does one launch with a stall? Am I doing something wrong? I am definitely missing something here. I'm still learning the in's and out's of this car so please help!

Here in Michigan are car with that similar work done sould go low to mid 13's
I know the weather will play a factor, and since your in HOT New Mexico it could have something to do with it. Although it's not humid there like it is here........

A tune is definately a must but you still should have had a better time than that. Did the car feel like like it was backing itself off? If you forgot to turn the traction control off and you started to spin it may have backed out of the throttle resulting in your poor time.

I sure it needs a tune but lets here more about how it stalls. If you were sitting still at idle at the track and you floor it how high will it stall? If your just rideing down the road how high do you let your car stall so it can run thru the gears. I'm not talking about flooring it but as if you were trying to save gas kinda feathering the throttle. I wonder if they sent you the wrong
stall.
Lets see some time slips. We can't help you till we know what needs fixing!
