Super Chips and SCT Tuner combined

I have an old Flashpaq model 3815 on my truck. Just picked up my SCT X3. The question is do I have to return my truck back to stock before putting in the SCT Tune?

YES... I'm not even sure the new tuner would install, but if it did, I could imagine you could throw your pcm for a loop with two tuners. I wouldn't risk it.

Ya thats what I was thinking also, but Running 265/70/17 tires SC was nice for dialing in your Speedometer. i Heard that was not on option with the SCT.......Am I wrong?

Correct sct does not do tire size. HOWEVER.... you CAN use the superchips to change tire size and if you touch nothing else, you can use the sct on top of that. Ive been doing that for nearly 2 years now. Changing the tire size and only tire size does not leave any imprint on the pcm. Then the sct is allowed to still do its job

Thanks for the feedback pepper. i already uninstalled my SC 3815, and installed 91 SCT tune. might return to stock and give it a try later.
