I want to get my pins turned on for Efans but I am not interested in getting a Full tune at this time (not sure if I am going to do anything to the 5.3 or swap to a 6.0). I am programmed with a Hypertech handheld and I was told by Jenna that I would have to ditch that to have my pins turned on. Which I understand. I am only running the 87 tune with the Hypertech but I am really more concerned with not losing the increased tranny pressure and shift point upgrades I am getting from the Hypertech tune.
So what I am wondering is if I buy a TCI Shift Boss controller would I be able to get my Efan pins turned on and be able to use the TCI controller at the same time or would it be just like the Hypertech situation. Thanks.
