im locking at 95mph.

i figure my lower MPH N/A is due to the nitrous tune. im shifting 6500 instead of my usual 7,000 rpm. 21 degrees of timing instead of 26. and then these +1800-2100 DA's arent helping either.

i have my tow haul button set up to not lock up under wot but i always seem to forget to test it out at the track. i know it needs to be locked on the nitrous. its like another gear when it locks lol.

The lower shift points, lack of timing, and bad air are likely your slow N/A issue's. I didn't even think of the shift point and timing off hand. Have you thought about buying a tuning software just so that you can go to the track and load an N/A tune and have a seperate nitrous tune? That would also allow you to log for Charlie. Just kinda thinking out loud/while typing idea's. Your truck has ran some of the better times for it's mods so far by just getting every bit of power you're making to the ground.

In case I forgot to say it, congrats on the new best time.
