The technology helps the newer trucks but the emissions equipment offsets the gaines. My 1st gen intercooled5.9L 91 stock ran from 16mpg to 22.5mpg withan avg of 18.xx. With the Aero Tonto my numbers are 21mpg with 2 100mi runs at 29.6mpg from Helena, Montana over the continental divide 6800ft passes to Anaconda, Montana and an avg of 24mpg. In April I ran from Albuquerque, New Mexico to Las Vegas, Nevada at 70mph and got 24.92mpg .
Adjust the nut behind the wheel and you can squeeze a cupple mor mpg out of it.
Use the Torque App (or similar) and monitor your IAT ( intake air temperature)and block your raidator till you start seeing an increase. Then back off 5%, open the hole 5%larger. The size of the hole will be different for winter and summer, and wether or not you have grades to pull, and loads over 1500lbs.
Based on a long conversation with a Cummins tech. 45-60°f is ideal IAT or as close to ambant if ambant is above 60°f can be 20-50° above ambant. Per Cummins for every 10° above 60° f there is a 1%loss of power. EG a 250hp engine will only produce 240hp and buen 250hp worth of fule. At an IAT of 90°f.
