    Help me make the best choice-

    Yeah, the Bully Dog costs $500 and includes Gauges AND a Programmer (that I really don't need 90% of the time as I am a conservative driver), and you're not the first to say a BullyDog can destroy your engine, unfortunately. If I have to shift down a gear, or climb a hill 20mph slower it's fine...

    Help me make the best choice-

    I recently returned from a trip towing my 8000 pound 5th wheel w/ my stock '03 HO Dually w/ 6spd manual transmission. My real question follows the narrative just below. One day I was climbing 6% slopes at 10,000ft elevation (80degF) in 4th gear no sweat and 1/4th throttle, and the next day...

    Big Power Loss '03 5.9 HO

    Yes, that's how MINE was until the described incident (except I never ever needed to floor it-1/4th throttle was all I ever needed-I could always go one gear lower and 1/4th throttle was enough the way I drive). On that hill in Utah, it couldn't hold rpm except in 1st gear WOT. Now, tell me...

    Big Power Loss '03 5.9 HO

    I hear you. Problem is that this shop (and the sister shop next door run by a friend who mostly specializes in Powerstrokes) have the reputation of being the absolute best diesel guys in the 25mi area. Their shops are full of customers who got screwed elsewhere and went to them as their last...

    Big Power Loss '03 5.9 HO

    Good question on the boost pressure. When I went to the shop, boost was my main thought. In fact, when I got to a safe place after the Utah incident mentioned, I looked for disconnected hoses or rushing air (from the turbo) under the hood, but couldn't see/hear any. That made me think of the...

    Big Power Loss '03 5.9 HO

    CP3 has 130k miles on it, as does the truck. Engine has 10k miles since total reman (prior owner let it overheat and scored 2 cyls). All injectors were bench checked to 24,000psi and found to be perfect at O/H. Engine runs exceptionally smoothly (zero shake at end of the long gearshift lever...

    Big Power Loss '03 5.9 HO

    2003 H.O, 5.9, 3500 Dually, 6spd Manual On a recent trip towing my 8000 pound RV, I lost considerable power on an uphill section (narrow, 2 lane road) to where I only topped the hill in 1st gear (6spd manual) at 2900rpm w/ the pedal to the floor. VERY scary since there was a cliff on one side...
