disappointment and confusion from the track today

[ShoverRobot]

i finally got a chance to run my car today and i had some weird stuff going on.
the first and best run looked like this

r/t .174
60 2.485 (got it down to 2.2 later still not good though)
330 6.348
1/8 9.149
MPH 80.98
1000 12.009
1/4 14.189
MPH 101.06

now at the end of this run i was near the top of third and thought i hit fuel cut but it was more like i just backed off the throttle really smooth no backfire no buck or anything. also my speedo sensor wire fell off.

i did a few more runs and everytime the shift into third the speedo wire would fall off and right when that happened the "fuel cut" would set in. i turned the boost down and added a little more fuel but that didnt help. i have no idea whats going on. i did a rough tune using the pocketlogger a few weeks ago doing 3rd gear pulls from 2000-7000 and i never had this problem.

How much boost are you running? You should be trapping higher then that with a 16g, sounds like a tuning issue.

19 at first then i turned it down each run after that it didnt help.
