Maybe more than 30rwhp...you will see and also hear some good gains with what you are planning and a retune. Keeping the flowmaster? Dual cutouts would be pretty sweet as well.

yea i plan to keep the flowmaster for now, i dont think that is holding me back at all, i think its the manifolds and cats... which hopefully the next time i go to the track wont be on there. i think i will do the dual cutouts, that would help ALOT at the track.

His 60' times in the 2.0's aren't that bad if you look at his trap speed. His trap speed is about right for a 14.2. With the wheels and tires he was running, I would have been able to pull off that time easily. With having a 5.7L, 3k stall, etc, I would say that he has some other issue's holding him back.

You were picking up 17 MPH or so from the 1/8th on. That seems sort of low. Check your injector duty cycle, I'm thinking you might be pushing it. What is the truck shifting at?

You might wonder if the converter is locking in too early also.

I might have a look at the tune something is not right. I am running the MT radials and if I do a small burnout using the water, I can hit it with a 100 shot off the line and not spin. I think you may still have some water or crud from the street causing you to spin. That being said your MPH is still off. I think you need to log a run or two and make sure your timing is where it needs to be. You may be loosing timing dow to knock issues. What RPM are you shifting at?

Quik said something about a percentage rate for injectors on what was safe and what wasnt... i think mines running like 97% or something and he said thats not safe. if i remember correctly i think its shifting around 6k

i was told to go off the line in 3rd gear and run it out like that. can Quik check where my converter locks up at by pluggin in to my computer or no?
