I agree with you about high speed travel in these rigs . I live in a very rural area and 99% of my driving is probably 10-20 mph range, all dirt roads. Every so often I do need to jump out onto the highway for a few miles to get to the next dirt road. Would just be nice to have enough pedal to keep from getting run over by a tour bus. From the hp/ torque numbersadvertised on this tune I could tell the stage 2 tune from KMS was lower than the stage 1 from vivid. Have been very happy with the other aspects of this tune. Has increased low end noticeably, EGR deleted, speed limiter removed, and I have a spare ECU. Everything as advertised. I guess its more geared to off-roading which makes perfect sense. Still just wish they was a little more on the top end
