Default Went to the track last night and had tuning problems, need some help

I'll post up my two scans and my tune, but first gear would rev up to my shift point at 5800, second was like 5000rpm, third was like 4000. WTF it didn't feel like wot which it was. Mods are in my sig, but i think it has something to do with the TQ locking, and it was like 100 plus *F last night and I havent touched my tune since spring when it was 70*. Please help cuz I'm pissed.

you need to disable shift lock. and under tcc duty cycle max it needs to be 99 and tcc duty cycle min needs to be 90. did you have your tow haul button on? by the looks of your tune you use it for your performance settings? cause your normal shift speeds differ from your shift rpm so, your shifts are not going to be constant.

yeah dbw, I thought all the TM is out, tow/haul was off. I was getting some KR driving out to the track due to the temps
