Thanks for the Prompt Reply, and an excellent website you have! So...its the wastegate!Any experience/tricks with loosening them up? Does the wastegate sound typical for the white smoke at idle and lots of black smoke at acceleration? Im relatively new to turbocharged (and diesel) vehicles, so my knowledge in this area is very small (but growing :P ) Thanks and take care!

Hey Guys, First post! I recently picked up an 02' Ram (in my signature) with the HO 245HP cummins and 6spd, it's got 100hp injectors and a 4" exhaust and no chip/tuner This last weekend, I went for a 250mile drive, and all seemed to be well and got back home sunday morning.Sunday afternoon, I was heading out for a drive and noticed some white smoke at idle, when warming up AND while warm while at idle. While under ACCELERATION/LOAD the truck will now put out more black smoke than usual. The truck was idling fine and nothing seemed out of sorts. Figured I'd pull a code so I quickly pulled over and checked and got P0234. I contacted the folks at BD diesel (they are local-ish and familiar with the truck) and they reccomended I clean the map sensor, but Ive been reading that it may be wastegate related? Anyway, All input is appreciated, i'm just hoping that it's not the VP44. :\ Thanks and take care! -Jeff
