Stacking as in double tuning? Holy ^%$& :O accident waiting to happen and by that I mean PCM waiting to explode! haha

 

Sean says he doesn't see problems with stacking, seen 3-4 failures out of hundreds of people who stack. I sure would like to keep my shift schedule.. it will be like a step backwards if I have stock shifts and all that power... Though, according to Sean, SCT does handle TM pretty well. I'm undecided, I will try just SCT and hold on to my SC for now.

 

I used a superchips cortex to adjust my shift points and stacked the SCT on top of it. When Sean sent me an updated fuel map my PCM corrupted. I had to have Superchips write me a new stock PCM map and had to reflash it. Once that was done and set to stock Sean took my new stock tune and I went from there. Stacking tunes = waiting for disaster.

 

Didnt superdak have issues too back in the beginning with stacking? I am pretty sure his computer also went nuts
