5200 wow that must be fun. i was thinking of getting a 2 step, what did you switch yours from the line loc or the pedal?? 60ft times are in the 1.6-1.7 range. does the m-20 seem to make the rpm drop off on the top end? i had one in my truck when i first put it together and then destroyed it and switched to an m-21, seemed to help on the 3-4 shift, and with 4;88's it still leaves hard. eventually exploded the 21, hopefully this one takes the abuse.

i did have a ta performance cover on before i put the rear brace on but then i had to get the cover from lpw to use the back brace.
