[QUOTE="flocksmonster garage, post: 1382351, member: 20347"] So this morning I set the truck to the lowest hp and tq tune it has. The exhaust has become a little deeper and kind of sounds like a 7.3 (less hair dryer noise). The slight "miss" is not as frequent or easy to recognize but it is still there. Also I noticed that at idle the RPMs fluctuate slighlty, if you really stare at the needle you can see it moving maybe 100 RPM, truck runs smooth and does not shake or anything, it acts nothing like the 6.4s ive seen on youtube with the surging idle problem where the idle is so rough it sounds like its going to blow up... -anybody have any ideas? and am i making a bigger deal out of this stuff than it really is?
