I have a rebuilt 7.3 with stage 1's d66 and adrenaline. My question is I have an old out of the box hypertec chip that was in my truck before the engine rebuild, can I put it back in the truck with out hurting anything? Currently I don't have the money to get a custom tuner for the truck and am running with no chip or tuner. I would like the power from the chip but don't want to hurt anything. I do have gauges now which I didn't have before the engine rebuild. I ran the truck for a day with it and it had much better throttle response and about ten lbs of boost more but I pulled it that day because I was worried I would hurt something.
