Truck won"t rev up!

Spickerman6.4 · Jan 23, 2014

Last weekend i did 30% nozzles high rev valve springs and lifters, push rods, 6oh manifolds. Took truck for a ride was turning rpms very slow, had little miss to it. Now it won't go past 1800 rpms. im waiting on tunes from innovative to see if its a tuning issue but wanted to see if anyone had any input on this.

Sounds like limp mode.

When they go into limp mode won't a check engine light come on of something on the dash? I'm getting nothing like that.

did you bleed the fuel system of air?

Spickerman6.4 · Jan 23, 2014

Yeah bleed it all out but it still seems like its starving for fuel. Eric is back in his office on Monday hopefully get the new tune and hope that's the issue

Does it maintain rail pressure? Any codes?

Spickerman6.4 · Jan 24, 2014

My monitor won't read rail pressure and its not throwing any codes

I didn't realize it won't read RP. That definitely makes it tougher to figure out.

Spickerman6.4 · Jan 24, 2014

Yeah it does so I'm just gonna wait till Monday for tunes for my nozzles and such and see what happens and go from there

Were you getting any smoke when taking off? If you were getting plenty of fuel (which I am guessing you are not) on 30%s nozzles, when taking off, I would think you should be getting some smoke.

Spickerman6.4 · Jan 24, 2014

Very little smoke

Well guys found out the problem VGT module crapped the bed. Got it all back together last night took it for a ride and all I can say is oh my god! Stock fuel pump had no issues keeping up with 30% nozzles as i can tell so far everything looks and the sounds with the 6oh manifolds unbelievable. very pleased with the build so far dyno run soon to see results.

What pw tune you running and was it holding at 24k-25k?

I'm running 330 extreme x tune from IDP not sure on rail pressure yet my SCT live wire doesn't read rail pressure but from what I can tell it had no issues running them. Very snappy and quick response

The LW will read RP in kPa.

If you can, find out the PW of that tune, especially if you are maintaining 30%s.
