Hey guys, kinda new to the diesel world. Got an 01 lb7, stock. Been driven it for a while and i drive gravel alot and like to get it into 5th gear and ride out the bottom of the gear. It used to gain speed goin up hills, but now with my foot on the floor it cant hardly maintain the same speed. Wont even jump up the RPMs. I feel as though it might have happened after i changed my fuel filter, but not sure. Also it is going to be going in for a new set of injectors in near future. Just got an MBRP 5in on, but that didnt make any difference. Really bugs me not knowin whats up. Please help me if you can. :help
