Post your slips... the times could help troubleshoot.

i lost the time slips but my 60ft was 2.1 on the 14.0
in 2.2 on the 13.5 trap speed was like 98on the 14.0
102 on 13.5 forgot my 1/8 but i think it was like 13.5 8.7...14.0 9.2 i think.also i had replaced the tensioner pulley in ideler pulley oreilys orderd the wrong idler in the mechanic told me he could make it fit it wasent to much bigger but it had more width in he removed some washers in shoved it on but the belt also had some slack in it was rubbing so the day after i went to the track i had mti remove that pulley in belt but it dont feel like it helped
thats when they told me about the tranny mount btw it was because of the a/c i changed those pulleys

Are you throwing any codes? If so which ones? You might pull your plugs out and check them. Also check your O2 sensors. When those go bad, the car runs like doo..

Could be just poor track conditions when you ran last..

If your trans mount is bad you are not going to get all the power tranferred to the rear wheels because the back of the tranny will be jumping up and down and so will the torque arm. Replace the mount and run it again.
