I completely agree with Leevon. Although I've never had Justin (Blackbear Performance) tune a 8.1/Allison combo, I have used him on all the LS engine trucks I've owned, past and present (two 5.3's and my current supercharged 6.2) and this is money well spent. I immediately noticed a difference in performance, shift timing, shift firmness - just overall driveability was improved everywhere with no compromises.
