seems a little low?

lower hp/tq numbers were before tuning it on the dyno

it was about 90 degrees in the shop so that could have played a part.

for those who dont know my set up:

383 ci 10.5:1 cr
243 heads (stock)
220/220 .551/.551 114LSA
90mm intake and tb
Ebay lt headers no cats 3in cat back
E-fans
running through 4wd, 4l60e, tb stall, 3.73 gears, and 33in tires

what do y'all think?
