Message: [QUOTE="Charles, post: 1376532, member: 103"] Well, I took some time to fine tune the program during the hotter weather and to dial in the pw and icp for towing and low rpm lugability with great results. The truck will confidently lug down near 1000rpm while driving around and still have sufficient available power to pull up most hills without issue, while not smoking. In fact, I was running around 22 to 23,000 or so gross and even up some very steep hills I rarely needed more than 1600 or so rpm to have sufficient power with excellent smoke control. On many hills I was running 1400rpm or so pulling that load without issue. On steeper hills required pedal would dictate a downshift and smoke was starting to appear at that rpm but by 1750rpm or so plenty of power was available. The 38R was easily driven deep into surge. Boost was plentiful, even with my leaking driver's exhaust manifold that came to me with a sheared rear bolt. Anyway, just wanted to keep updated files flowing. This program is reaaaal nice to drive. And it hauls out pretty damn well for a crew cab longbed PMR on stock 4R100. It's a tow monster. With compounds the potential would be nuts. I plan to see about feeding a thermocouple into the PCS for an EGT reading with the 38R. No smoke, so you imagine it can't be too hot, but then again I've never made this kind of power sub 1700rpm with a single either. [/QUOTE]
