i am getting the jlt cai from brenspeed soon and i getting i think the 89 perf. 91 torque, 91 perf. i was just curious on everyones opinions on the feeling of each tune. I would think that the torque would give it more power all the way through to the power band and the perf. would be more power in the that band. am i wrong or what? opinions?

 

4 words of advise....more octane... more performance!

 

i drive 80miles a day for work so i wont be going 93 plus here in kcmo area i am not sure i cant get 93. there is a place near my work wehre i can get 91 at same price as 89. i am just curious about the diff in tunes.

 

If you can get 91 for the same price as 89, then get the 91. I have personally only used the 89 tq tune. I have read the difference between the three is tq tune gives more power down low and less up top. Performance gives less down low and more up top and race is a combination of the two. According to Doug there is about a 1-2 rwhp difference between the tunes.
