Hey all. Just checking in to see if anyone has ever compared the "canned" tune sold with the SCT XCAL II tuner and JLT II CAI system. I have been reading that the canned tune is ok but that a tuner like Fred at Evolution can get much better performance from a custom tune with this combination. I have been very happy with the canned tune, but would like to hear if anyone has found that a custom tune is better the canned one. By the way, I am running the 93 octane tune in my 06 automatic vert. Thanks!
