Boosted (SC) 6.0L and cruise control increasing automatically

Vehicle is a 2015 Silverado 2500hd 6.0L (E78) with a Supercharger installed.

I don't have alot of info from this guy but he is saying that his cruise control isn't working right after the blower install. He states after he sets the cruise it basically increases speed when cruise is set. Ive never run into this and was just curious if anyone else has. I'll add more info as I get it. Thanks

Even though this is a PFI motor it should really go in the GEN 5 section.


If this is a PD style blower magnacharger, LT4, etc. You should look into getting a SCIAP sensor on it. It will fix the the situation where they use too much throttle while barely touching the gas at cruise.
