Anyone else have a surging issue with the Juice on 6x6? It's only when 1/2 throttle or so, not when wide open and under load. Any thoughths?

 

Mine did that when it was stacked with a Superchips. The problem was I had two boxes fighting over who was going to add timing. you dont have another timing box stacked with it do you?

 

mine only did it when stacked with the smarty, timing or not

 

I had a Hypertech installed before but removed it when I sold it. It would not have worked in the buyers truck if it were not removed from mine, correct? Other than that I'm stumped here, only seems to be on HOT level 6, not the others. Just replaced VP and injector lines and no codes are present. Do y'all think it's the cold weather? I had read that the cold temps advance the timing?

 

could it be the same reason why the adrenaline guys are having surging problems.
