ABSOLUTELY!! I have a 10 level adjustable Powermax3 and 275hp RV injectors on my truck and I tow all the time. When I'm towing I run it on level 2, 3, or 4 depending on whether I want to worry about my EGT's or not. On level 2 I don't even have to look at the gauges, level 3 I only have to watch it if I'm WOT or uphill, level 4 I have to drive by it (great for passing on 2 lane roads with the 35' TT behind though)! When I'm not towing I run on level 7 most of the time and when I want to play (or race) it's on level 9 - on the top levels it's best to just not watch the EGT gauge! However, on those levels you're never at WOT for more than 17 seconds because that's how long it takes to go from a stop to redline in 5th! I did have to upgrade the clutch of course. I've towed up to 12,000 lbs with this combo.
