tuning questions

I'm Paul Lipowicz, you just sent me a cold weather tune for my truck with the nitrous...... i went to the track, and my mph is suffering bad... 12.5 at 109 compared to 12.1 at 112, and it's been this way ever since the PI 2800 stall..... I KNOW it's not your tune, but what i'm noticing is that the convertor is locking up at the top of second, but then unlocks sometime and relocks in the bottom of 3rd and it bogs down... what can we do??? I've heard that the best 1/4 times are achieved by having the convertor lock at the top of 2nd and stay locked the rest of the track

Please let me know, because the summer season is coming up and my next step would be to pull the convertor, put the origonal one back in and go back to my 12.1's at 112, but i dont want to do that, i want 11.90s at 112+! lol
