if it was fine a 6.0 with 11.1 cr and a decent cam would be 370-400 hp, not 326...

Might just want to wait for some better weather and see what it does. I've seen some 12.8s@101 posted on here. Hell, Bluecajun was running 12.40s with a 104 trap.

There is the graph... Thats and unlocked converter stabbed at about 3000 in third.

if you put my track times and the fact that my truck weighs 4600 with me and 1/2 tank of fuel into stupid internet HP calculators it says it should be about 385-390 to the rear wheels...
internet calculators are junk. stick to sae dyno numbers (no matter what HP number it gives you, look at the curve) and track times. keep track of the DA on track days by the hour. like i mentioned in PM. your curve looks weird to me considering the mods. very flat and your torque peaking so low is weird to me.

just looking at the tune isn't really going to help in all cases...... You could be getting some burst KR off the line thus murdering your timing, thus killing your 60ft.


BTW, what altitude are you running at? is that PT converter big in diameter? That might explain your 60ft, but i figured your MPH would be higher...

Right, and most reg cabs he's being compared to in the 12s all have better 60' times. But then again, most aren't running towing converters either.

converter unlocked and his high elevation can account for alot of it. what im saying is by looking at his curve, it help get him out of the hole for sure being that its geared better, but it's not going to put him at any more power since it just about flatlines from 4500 to 5500
