i know I am ressurecting an old thread here, but i am basing some of my tune off this tune (found in the regisrty) and was wondering if anyone including the originator had any imput. The PE, Torque Management, fans and ancillary things were all in line with what i was doing, but i am still too new to be really comfy messing with timing tables and fueling on my own (just that pesky power stuff lol) so i was going to borrow the info in this tune as a starting point.

I tuned one of these cars last night at the 1/4. The torque management makes a good difference. The owner for some reason has no interest in running 93 in it so i didnt have much room to play. I experimented with some cam adjustments and knocked off about a .5 second with that alone..... not much when the car was running 17.5s before... I was able to get 19* in the mid range and about 17* up top. set the shift point to 6700 and raised the pressure a bit. Gave it a good firm shift that felt safe. leaned out the cat overtemp slightly and richened the PE up quite a bit up top. In the end it was running 16 flat consistantly and could have been in the 15s with a driver mod. Was my first 2.4l vvt motor so wasnt sure how far you could push it
