ok guys when im getting on my truck on the interstate it seems to hesitate a little bit and stumbles it really seems like i am running out of fuel. i have a fuel boss lift pump and the smarty turned on sw9 rp2 tm3 timing 1 wastegate off built trans with tripple disk when im cruising and put it down at about 70 it will not necessarily stumble but it just seems like it isnt pulling as hard. the rpms are about 2000 and from there up it just seems like the power isnt all there is this because im past the power band? im gonna adjust the smarty down to sw8 and see if maybe im getting tomuch timing and then to 7 and go from there any suggestions would be great thanks oh i have 3.73 gears as well

What are you running for FP or RP? Boost? EGT's?

SW9 is a lot of program for a HE351.

TM3 isn't too much for timing, its not the most advanced.

yeah i know its a lot for that im gonna turn it back down to sw 7 and try that i have my torque management on 3 not timing!

What is your FP and RP when this is happening?

i dont have a rp gauge but fp is 17 all day long i turned it down to sw7 and the truck seems a lot stronger now really

You were probably trying to push more fuel than your CP3 can handle.

I would invest in a RP gauge if you want to run other than stock rail pressure.
