It ain't no speed demon, but it does just fine. I have steep hills in PA where I go 32 mph up the hard stuff, but most of the time I go as fast as I feel comfortable. Backing up @ 63 ft total is almost more of an issue, but that's just a driver ability issue. I bring it up to speed steady, and keep the speed constant as much as I can. I am now looking forward to longer, and more traveling this summer. I like the idea the TS controller just raises the fuel pressure, mine has the adjustable control, and is easily removable. I bought mine from TS Diesel performance online HTH HJ 1 800 816 6985 last number I list
