Just installed Superchips tuner today and truck does not cut out at full throttle but when accelerating at 1/4 pedal will cut out and come back at about 2200 rpm's. What would cause this? Also I have not installed a Pyro yet but I am running on safe tow mode and not running hard should I be concerned with temps. I have an infrared temp gauge what would be difference between internal and external temp reads on pipe 6" below turbo?

 

Better check your lift & injection fuel pumps.. mine stuttered because of bad lp

 

Just had a new lift pump installed about 2 years ago had a cold leak on a 8 degree morning. Truck only has 54,000 miles.

 

I had a stock replacement pump go out in about 20 minutes of driving. You never know how long the stock pumps will last. That is why I now have a Holley pusher pump. I also had a stumble that was caused by low fuel pressure. After I installed the Holley, it went away. You could also try to reset the APPS. There are instructions in the tech facts area at the top of the page.

 

I'd use the Superchips to check for codes. And hope you don't have an 0126.

Mileage dosen't seem to matter much with the Carter/VP-44 failures. Unfortunately.
