Well I went from 13.52 to 13.17 and that was with taking off the serpentine belt though.. ran a 13.32 with just tune...then I took out pass seat and serp belt...run 13.18 then I added another degree on the low end...and it went 13.17 but I accidentally rolled in to deep which killed my rollout and therefore about .02
I would have still been tuning it to go faster and faster but it was 10:30 and track was closing....
I bought a cable from
http://www.akmcables.com and the program I use to tune with..LT1 edit was from
http://www.carputing.com I bought the expert version..I spent 2 hours making a few tunes... took it to the track and found out which was faster...and worked on that particular tune from there.
But if you have a 96 you will to switch to a OBD1 computer becuase a OBD2 car has alot of quirks that make tuning a pain in the ass...and the stuff to program an OBD2 computer is twice the cost.....
You will acutally save money by buying a OBD1 computer for $150 and the stuff to reprogram OBD1 for $300 total
If you want my tune I will send it to you free of charge once you are set up...
instant 2 tenths I can guarentee you.
