Can any one tell me why my truck bounces off the rev limiter when shifting from 2nd to third?? Diablo Intune teams shift firm

I used the Diablo flex tune and I currently have a tank of 93 in it can't wait to put some e85 in her

I tuned mine last night with the Diablo Intune and it makes a heck of a difference!!!!!!

And I left the truck tuned when it went to the shop both times and I would've returned it to stock but it's kinda hard when it's on a tow truck and your tuner is at home in your underwear drawer so if any of y'all are worried about tunning your truck I would like to think that it would be okay I have since traded that truck in on a new Sierra 4x4 and have already tuned it with no regrets or worries what so ever

I had my transmission got out at 4,500 miles and I had a Diablo canned tune on it and the dealer never said one word about it @11,000 miles I had a lifter fail and they never said one word about it, nothing! Needless to say I was worried to death about it.
