So disappointed after I drove it up to AK from IN that I took it to Peterbilt and then to Cat just to make sure there wasn't something wrong with the motor. Unfortunately there wasn't, and neither recommended any mods because the motor is already pushing 330hp and that was the max it could handle. I will say it has been reliable as I pull the guts out of it almost daily in the summer getting to our job sites on the hillside. Looks like we might be able to replace it this year. Hoping for 425hp+ and a jake.
