Hey y'all. I'm final a cummins owner always been a big fan just never had the money to afford it. Bought it with 138000, everything stock on it. Only problem is the 4 speed automatic transmission, a little slope downshifting from 2nd to 1st I think. But I knew those transmission built up anyways. I know the basics to most truck but want to learn a lot more. The only mods I'm really interested is increasing mpg and engine life. Not really looking for tons of power. If you guys have any pointers or brands or good deals. With some mods I'm looking for (cold air intake, tuners for mpg/shifting points, exhaust, ect.) I'd appreciate it. I know how to work on the basic of a truck but I don't think I could do much ripping it apart. Right now anyways. So if its something more advanced ill need a little more explaining.

Thanks a lot
