Same problem every year. We take dad's truck , 5th wheel and boat north. The truck has a Flashpaq set on tow , exhaust and a K+N filter kit. The tranny temp is cool , engine temp is fine , but when pulling a hill at 60mph , engine reving at 1900rpm , I lose power. Rpm's are still there , but no throttle responce at all. Even shifting gears makes no difference. After about 30-45 secs , things re-engage and we're off. Trailer is only 24ft and boat 17.5ft. I did get a code twice - PO234 - engine overboost condition ? Truck has 130k. Please point me in the right direction , or any direction for that matter !
