Hello to all. Wondering if anyone can steer me in the right direction. I have a 2000 GMC Yukon slt 4wd with 5.3. Cats were plugged so I deleted them when I did my long tube install. Also did cai, and egr delete. I have 1 7/8 speed engineering LT’s going to 3 in x pipe with a foot or so of straight pipe Out of the x to dual flowmaster outlaw mufflers with turn downs dumped out before the rear axle. Truck starts and idles great. Something is definitely wrong though. I don’t know if all the tables are out of sorts, or maybe not enough back pressure? Runs up to 40-45 mph great then it hit a wall. It’s like it wants no gas or all the gas but no inbetween if that makes sense. Definitely smells like it’s running pretty rich. Maybe need longer exhaust and tuning? Anyone want to chime in. Please and thanks!
