Message: [QUOTE="Montucky, post: 1296367, member: 23541"] The egr valve is still in it. The cooler is gone though. The code was a P401. Insufficient egr flow. I've just been using the 50hp tow tune. Backed the shifts off a little to -10%. Really like the tuner. Pretty familiar with the tech for the obs 7.3 since that's what I had last. The x4 seems pretty advanced as far as the available options. I just had gauges and a TS chip with PHP tunes in my 96. Tried out the street tune just for the hell of it. It had just got done raining/snowing and the tires broke free pretty easily from about a 15 mph roll and again from first-second. I plan on just leaving it in the 50hp tune until I get the studs done. With winter here, don't plan on towing the boat or camper much. Thanks again for the help guys. [/QUOTE]
