What RPM do you launch with?
I maintain the same RPM all the way down the truck...about 3200 or so.

 

When I come out on the clutch completely about 10 or 12 feet out,it's usually on the Rev limiter!!!! Then rest of t he track,pulls hard to about 150 feet then it seem like it quit gaining speed like the tires and the sled are going the same speed!!!!I really wanting to get where I can pull it in 5th low and see if it will spin faster,but it doesn't want to light the turbo real easy,but in 4th anyone could drive it,just slip it 10 feet and mat it,and your off!!!

 

We need more RPM with the fuel to back it.
After about 3200rpm my truck is not making power.
I have been launching around 3000-3200rpm and have had good luck.

Yes, I want more wheel speed too!

Are trucks are pretty similar.

 

We do need more rpm, its not going to be easy though! The cummins ECM is going to be tough to crack, its incrypted like crazy!!

I wish someone would figure it out,I'm tired on testing all the new stuff on my truck,I've had so many boxs,and programs that I'm not sure anymore what's best,I'm a beta for the new ez love it so far and when they send back the new 180 program I thing it's going to give the TST a run for the money!!!!!
