ok so i got my car tuned after i rebuilt the motor over the winter. Its a 2001 trans am ws6 with mods as followed

-5.3 bored to 3.903 347 with forged weisco pistons and eagle rods ls1 crank
-patriot ls6 heads, comp gold 1.7 rockers, hardened pushrods, patriot dual springs( used from my old motor)
-232/236 .615 114lsa used cam from old ls1
-ls6 intake, stock ported throttle body, 30# bosh injectors
-dynatech longtubes,slp y pipe with high flow cats, slp loudmouth

at the time the car had a t56 in it a week later i swapped it out for my turbo 400. The car has all bmr suspension components lca relocation, tq arm, drag bar ect.

The car made this power on a mustang dyno. After i installed the turbo 400 with a 4500 stall i brought it to the track and it ran a disappointing 12.2 at 113mph. I just want to know your guys thoughts on this graph, the cam is supposed to be making power up to 6500 but as you can see it stops at 5800. Also somebody lets on this forum said the a/f looks wary off. Ive been thinking i have valve float issues because i used my patriot dual springs from my old motor. Please give me your opinions thanks

What is the shift leg on your stall?? They TH400 and Stall will be more parasitic than your T56. What was the Track Conditions, Your 60' looks pretty poor. Is the car bogging with your converter?

I was leaving of the foot brake at about 3000 rpms the car felt like it was pulling really hard off the start . The concertor is a coan with a 4500 the car does have a trans brake but I wasn't using it because of the stock rearend . The car has really heavy American racing rebel 18" rims with Hoosier drag radials . It didn't spin at all
