At least it looks better with the fast intake and bogarts lol. I wanna see some 1/4 mile times with the new setup. Wasnt your 7.72 in really good weather? What were you consistently running in the 1/8 before?

 

my 60' was 1.68 which matches my last personal best with a 125 shot out of the hole.

 

last personal best, but you have 60' a 1.68 before on the old setup right?

 

What's your compression?
Looks like you need to increase the mechanical advantage on that pig i.e increase compression or gearing.I would shoot for compression first.I know its not the cheapest idea but i think you realize no idea other then dialing in your tune is gonna benifit power at this point.

 

You really need a data log while you're running at WOT. If your ETC tables were not modified in your tune, your throttle could be closing at WOT because you've exceeded the Max MAF airflow or max ETC airflow. This happens a lot with Corvettes.

You need to log the truck and see if your throttle is staying open 100% the entire run. You need to log to see if your timing is good 100% the entire run and of course you need to log the air/fuel to see if it's good 100% of the way.

 

11.0:1 compression. it's a cable throttle body so i know the blade is open all the time. the other stuff is questions for wheatley. im sure he covered all of that stuff though.

 

I'd bet its due to the torque you lost below 5500.

 

nope. best 60' on the fuddle was 1.69. i did 1.68 with a 125 out of the hole, but it was summer so i was only cutting 1.80 60' times that day N/A

 

my truck spends about 95% of it's run above 5500 rpm. im cutting better 60' times so i dont see how the below 5500rpm rule applies here.

 

throw the 4.56s in and see what it does
