Is anyone running the Xcal2 from SCT? I used it with great success with my Lightning, but I remember I went mail order pcm with my LT1....I'll mostly be looking to tune for a full bolt on cam car.....maybe tune for a 75-125 shot down the road. What do you guys think of the Xcal2...or is it all but un-used here?

We sell alot of them. They are pretty good, and there are tons of happy gm guys out there.. But it depends on the person putting in the tunes. They ship out blank. So the tuner has to put 3 of his tunes in them.

The thing I liked about the Xcal2 is (unless its different on the GM one)....I can pull some timing or play with fuel if I decide to spray one night, and go N/A the next. More flexible than just a programmed PCM like I went with before.

I recently heard about this as well. It seems like a perfect fit for the N20 guys. Any other opinions?

Nitrous tunes can be put into them also. That even based off of shot sizes.
