Please help me
So, here's the latest. I retuned the super chips to stock and the surging problem went away and I could get up to 25 lbs of boost with no surging. Then I reprogrammed it to performance and got up to 28+ lbs of boost with no surging, but was afraid of hurting the engine. I then reprogramed to performance tow and BAM, max 18 lbs of boost, surging at that rate and after shifting without overdrive engaged 18lbs max boost with continued surging!!
Almost feels like the govener was kicking in.
This has me totaly baffeled along with a couple people in the know, doesn't make any sense.
I'm going to call superchips to see if my programmer has a fault in it's program when in performance tow.
Another thing I've noticed recentley was the battery light coming on and going of. No codes present for anything.
