[QUOTE="Chvyrkr, post: 245620, member: 169"] I ran my PMR motor on one tune, and one tune only, from just over 200k when I installed 160's, until 230k when I swapped a forged motor in. It ran perfectly when I pulled it. That tune trapped 93 in the quarter, at 8000lbs. Heaviest trailer was well over 12k, and was not an issue as long as I kept boost up on the hills. Regularly pulled 8-10 trailers. 80mph, 15-20lbs of boost, and 1100ish on hills. Was easy to do with a little gauge watching. Jonathan @ Beans, FTW. [/QUOTE]
