I'm missing MPH in the 1/4

Well i went to the track last night and was not very happy. I had a best motor pass of a 12.91@109. With my mods i should be trapping around 112-113. Any help anyone?

Mods: torquer V2 113, Mac mids, !Cats, Borla CB, Lid, Ported TB and MAF, 3400 stall in a 4l80, MT ET DR's, full rear suspension. AGX shocks all corners, battery to the trunk

Car is a 02 T/A vert probably weighs around 38-3900 with me in it.

Prior to this I ran a 12.82 with it. On that run i had a break in the TPS wire and it fell on its face at the 1000' mark. Car Didn't 60 well but my MPH should be higher then.

Why are you running a MAF if you are going to leave it failed? Did you do that on purpose or did you forget to enable it after the VE table tuning?

Engine Diagnostic - Air Flow - MAF Fail - you have it set to zero, set to 13500 if you want it to work. Reset the DTC's for it also.
Go tune you MAF after that, post a log file also.

that definitely sounds slower than it should. Do you have a scan of a wot run?

Not right now, waiting to buy A new laptop in a few weeks.

I fixed what LT1bird said and now I have to wait for it to stop raining so I can go check the maf tune.
