[QUOTE="6.7 Powerstroker, post: 1467158, member: 25084"] I re-tuned the truck by redoing the load first tune then the tow tune and it runs better. RPMs don't fluctuate when I stop like it's cutting off but the spooling is still lacking right now. It makes a weird noise before spooling up like it's hissing. I also noticed some soot on the passenger side of the turbo so I removed the intake piping and the turbos heat shield which was coated on the inside of it and checked all the clamps on the up pipes and down pipe and they all seemed tight. Looks like the soot was coming from the passenger side of the turbo but I'm not sure how that is possible. I loosened the clamps then spun them a little making sure the pipes were fitted correctly which they seemed fine then tightened the clamps and cleaned all the soot. Took it for a ride about 10 minutes and didn't notice any more soot but it was still making the hissing noise before spooling. It makes the sound more at low speeds then when it starts to spool up and I don't hear it at all. Could it be something with the veins? [/QUOTE]
