Jack,
Thanks for the input! The runs were actually pretty consistent. In fact, after the runs and looking at the AFRs yesterday, the dyno guy, an experienced tuner himself, told me that the Unichip's tune was really good and that I should stick with it
The Borla UEL headers I ordered should be here in month. Will dyno again after the install and report the results here.
Overall, I'm glad I went with the Unichip!!
