Don't flame me! The spark plug thing was just to get people to come say hi lol. I used to work on specialized heavy equipment for railroad construction (diesel obviously) but now I'm a railroad conductor in the Chicago area. Recently totaled my 01 Cummins and replaced it with a LBZ DirtyMAX. Came with a dsp5 switch and efilive but the dealer that took it in on trade didnt know that so I got a decent deal lol. The ****er gets up Here to gain some knowledge and maybe meet some locals. I need to rebuild the front end since it pulls so hard to the left when I launch in 4wd that I damn near wreck the thing hahaha. I see that dead horse has been beaten several times so I won't ask until I've thoroughly used the search option, although there seems to be a lot of conflicting info on the subject. But, show me an automotive forum where there isn't more than one school of thought on EVERY topic. Came from the AWD turbo gas world before I got my Cummins and wrecked it, so I know a little here and there but am not a guru by any means. Anyway, thanks for reading, I'll be around.... .
