Default C4 mod result with intake+exhaust+HyperTech

Ok guys, i used the G-tech on my bone stock LT1"Auto 2.59", but i was running 315's rears/ 275's fronts "Dunlops", the temp was about 70, stock tire Psi, Here are my results

----------- 0-60 1/4mile trap speed
stock best: 5.32 13.88 @ 105.1
with mods: 5.07 13.63 @ 107.2

I had the traction control turned off on all my runs. the tires still spun, i am sure with more practice and colder weather, i could hit high 4's to 60mph and mid 13's at the 1/4 mile

Intake was the Vortex rammer with Flowmaster exhaust
the 3 parts cost me about $1,100.

My next step will be a shorter rear end

So you picked up about 20hp.

Now cut back the spark plug ground electrodes and see how much you pick up.

Yes, I think your rear end is keeping you down also!
