I was towing a trailer about 13 k #s yesterday when my pedal went dead.
I was not under a hard pull when it happened. The throttle angle was about
20% , and it lasted about 10 seconds. Then just as abruptly as it had happened it went back to boost and started pulling again. It happened about 10 times ina 20 mile stretch. I tried the edge on 1 and 2 , the quad tow tune and it was the same on both units. It has never done this in the stock mode. And it has never done this before with the tunes . It seems to me that it is running out of fuel.
Any ideas anyone, My guess is a rail pressure dump valve, but the cp3 ,is also suspect to me. I have never had the check engine light come on.

Mine "use" to do it all the time with the Quad tune.Did you completely divorce it? Also check for soft mass air codes.

Today it did it on the xlerator. Will my quad pull soft codes ? Ill check with the Tech 2 tomorrow.
Its done it on all three manufacturers power upgrades, but not stock.

Edge too? What version do you have the newest?

I'd start by cleaning the mass air sensor with a contact cleaner non-lubricating.
