6.7L Cummins Forum

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.

I have one and I love it, with the egr unpluged and the tuner set on level three i'm getting 18 mpg in town!!

I don't know anything about this model. Hypertech had a bad rap for a long time on not living up to their claims...imho

I had the Hypertech on my Duramax (that I sold for an 09 6.7). I had guages before and after adding it. The power was significantly up but so was the EGTs. Without the pyro I think I would have smoked the motor. Mileage didn't change. I am not adding anything to my new 09 as it runs fine pulling my 18k RV trl and I don't want to mess with the warranty.

I have a 2008 Dodge Ram Quad Cab 4WD 6.7 and 68RFE. I have had the Hypertech for about 6 months and like the power but they don't have the option of changing trans. shift points or firmness. The shifts are mush with the Hypertech and when the torque convertor locks up it doesn't lock right away it feels like it engages slowly slipping all the while under any throttle setting. Just as a check to see whether it was a trans problem or the program I returned it to stock and the shifts firmed back up. Load the Hypertech back up and the shifts are back to mush. I usually let it shift up to 4th gear with the convertor locked before I roll onto the throttle. There is a strong power increase with my truck, it seems like it accelerates as hard in overdrive as it does in 4th with the stock programming. With the EGR unplugged Volant filter with scoop and 5" exhaust from the DPF back I average 17.5 combined and 20.5 on my last trip to Houston from Lafayette, La. with considerable stop and go driving on I-10. I like the Hypertech power but hate the shifts. I am leaving the it stock until I get a shift kit installed then I will re-load the Hypertech. I am going to contact Hypertech support to see if anything can be done about the shifts.
