Never really noticed this with my stock exhaust and muffler delete but now with my new exhaust I can hear a whole lot more. To describe the sound its like a clogged carb on a gasser. It only does it under acceleration and while boost rises. Ex. Going up a hill doing 60 with cruize set, boost will climb engine will get louder and will start to make this sound, almost feels like its running out of fuel and slowly loosing power. (No jerking or surging going on) Just seems to do it when ever the boost gets above 15 psi. I put the black international 1821720C99 CPS in 5k ago. Just changed oil, I have been running Rotella 5-40 for the winter. Changed fuel filter then too. Always starts up fine, nice idle and fuel millages is ok for the winter at 13 mpg. Truck has 120k on the dash. I have access to a scan tool, anything I could look for with it? Open for any suggestions. Just want to throw this out there because I am going on a 1500 mile trip with snowmobiles behind next week. Thanks guys.
