Bouncing off redline?

[Big Mike 74]

I have a 2013 Sho with performance package with the 3 bar Lms tune and I was out with the car last night with my buddy and on more than one occasion when I hit the gas it bounced off redline before it shifted....anyone else experience this? It happend once from 1st to 2nd and twice when it shifted at 80ish....the car was in sport once and regular drive once
..however it sits under a cover for about 2 weeks per month before I take it out

We're you in D or S? Did you touch the paddle shifters? I don't believe it should do that...
My 11 PP would NOT shift at all and keep bouncing off the redline if you were paddle shifting it, but I think they changed that in the 13+

I was in sport mode and once it happend in drive its like the car glitched up a few times

Yes I have experienced this tuning these cars. Usually a bad write on the tune. Happened to me numerous times during R and D. Try restoring to stock, updating your tool, reload the tune to the tool and rewrite. Or ask LM send you another copy of the tune.

@All_Grip that is incorrect.

That is the TCS not allowing the shift because of the situation the car is in. If it senses a lack of grip combined with steering angle and throttle positioning the car will not allow you to shift. That is part of the car's factory logic. The factory tune does not allow for the same power as our stage 4+ and 4+x tunes.

It's happened to me in first gear and I'm running an LMS tune.
