something is not right
My exhaust back pressure is way higher than normal. 310 tune was hitting 58 lbs of boost. Dropped to the 250 tune. Boost was normal but the back pressure was still high. Dropped to the 150 tune. Boost at 50 mph cruising down the road was 20lbs, EBP in the high 60s. Not towing just driving flat roads. Just doesn't feel right. Seems to be struggling. Only 23k on the truck. Mostly driven on the 250. Any ideas?
