[Rock hound trucking]

good day rawze i have learned more from u then any one thx for your site and vidios

i have a 2008 prostar cummins isx 500 i did my owen parcial delete on the dpf filter i was haing trouble with it regening all the time so i took the diff press sensor for the dpf and welded a nipple on the back side of the cat converter and put the front sensor there then i nknocked out a 5 inch hole in the filter pretty much just tricking the computer to still have diff press this worked very good never lost power or fuel milage . the truck would regen when the cat would start to sout up once every 700 miles to 1500 miles for a short time i drove the truck this way for 65000 miles with no trouble at all . then my egr cooler cracked . the international dealer talked me in to doing a dpf and egr delete know i can not get any booster over 34 psi un less i am in low gear and pulling hard . i have replaced the accuator on the vgt pulled my turbo apart cleanned it up spot less repaired all the fins to spec with the vgt turbo kit every thing lines up good when installing the accuator checked for leaks on the system tried a new imap sensor inspected the exagust manifold for leaks and cracks have pretty much done everything that can be checked mys next thing is im going to cover the air in take on the turbo and press test the whole system again thinking i might be loosing boost throw the turbo back in the crank case i did drill a hole in the top corner of the crank case filter so this would eleminate a high crank case pressure fault plus there is no blow buy but u can tell when just on high ideal

any help would be great
