I am going to try a sd tune. I have a 2002 pcm and I was wondering if their is any advantage to using it over my stock 2000 pcm. I was also hopeing for some tips and tricks. I plan to follow the sd tutorial and hope not to blow up my trusty 4.8l.

 

I just got Live about 3 weeks ago and I love it! It's just a learning process, be sure to join up on the EFI Forum.

 

First thing is do no use the SD tutorial in boost. If you want to use that, then I would tune the truck and NEVER hit boost. If you do, then you run the chance of it being really lean. I would suggest in going to Custom OS for 2bar. You will have to replace your map sensor as well on the manifold if you haven't already.

As far as the PCM, it really doesn't matter as they are all the same. I would start with a 2002 OS that is for your vehicle and go from there. If you need help setting it up, let me know. I have one I am going to setup later tonight for another member first and then I will be free to work on others.
