What’s up everyone! It’s been a very long time since I posted here, but this is the best place on the next for this type of knowledge and I need some help. I’m not very versed in OBDII PCMS but I picked up a 1997 k1500 5.0 4wd truck, the kid I bought it from put a crate vortec 350 in it.

Since I bought it I put a lift kit and 35s on it, and my msd ignition. I also basically turned it into a light duty 2500, with my 14 bolt semi float, rear 2500 springs, and geared to 4.88 out of my other lifted truck.

I was wondering 1) can I get a computer from the same year(s) truck that is a light duty 2500 with a 350 and use it, if I can what code computer would I be looking for and 2) I’d like to reprogram my speedo, and would like to know which tuning software and hardware comes recommended for the OBDII trucks.

I have tunerpro already ready bc I had a moates setup on my 94... thanks for all the help in advanced and thank you for having me back!
