I can see it working but nothing like what an actual tuner can do for you. The procal will still be in a real safe area for warranty aspects. Plus it's a one for all. Just like buying an xcal3/4 with canned tunes. You might feel a difference but it won't be the best.

I've seen a few guys that were 100% stock but ran a 12.2 on on a sticky tire.
