My car was pretty quick for the budget kit i had also.I used this setup:
13g turbo(1g dsm auto)
ported hf manifold
450cc's with afc hack(also untuned)
2g dsm intercooler
1g dsm bov
stock auto tranny
walbro 255
2 inch charge piping
ebay plate
I never ran it at the track and did 5-15lbs of boost when i had it.I'm guessing similar times to yours in the 1/4.As far as beating the ta i'm with u man.I raced a modded ls1 ss on a 60+roll and hung with it till the crxs top speed.When u get some tuning i dont see why u cant break 200hp and high 12's in the 1/4.
