Anyone here had experience with the Hypertech Max Energy programer on a 6.7 Cummins. I like the Max Energy over the E-Con because of its extra program options. They offer simplicity, ease of use and fuel economy claims. I have gauges and I'm not planning on losing the DPF.
The truck is stock other than a gutted intake tube, an after market drop in filter and an open bottomed air box. It is an '07 4x4 QC with a 6 speed auto.
