got my xcal2 on sunday. it rocks!!!!! i only have 200 miles on the 91 max so far, so it still has to do its adaptive strategy. it pulls super hard from 3500 to 5400 and as it shifts, it just launches even harder. can't wait to do the datalogging and fine tune it a little more. still have yet to try my 91 tow and 87 max tunes. i really recomend this bad boy. its really worth the money. oh yeah forgot: my dads got an 06 extra cab powerstroke f250 with a workhorse cpu. we raced when he got it and he easily pulled me. now we raced again: dead even. OH YEAH!!!!!!

 

See now why couldn't I have that kind of result. The shifts felt much firmer (+1), pedal felt different (no power until you floor it, -1) and I lost about just as bad as I did to a buddy's chevy, as I did pre-tune. I did perform better but our stock tuning is always going to be different than the next guys so the effect on our trucks are going to vary. Congrats on your investment and I'm glad it worked out so well, you seem so excited.
