Hey everyone-

Ok well this is the story I have moved from the 6.2l diesel section because my 1987 Suburban blew up and i am tired of dumping money into it so its going to be a parts rig...

Anyway my NEW (at least to me) 1999 K2500 suburban 6.5L diesel with 100k on it just pulled into my driveway and shop...

Now I am excited to put on some upgrades to get the best combo of power and towing ability as well as mpgs...

SO ANY SUGGESTIONS ON WHAT I SHOULD CONSIDER DOING TO IT....?

It was regularly maintenance and has no issues, the past owner is the original and a good friend of mine...

I was thinking of 4 inch down pipe/ exhaust, cold air intake... And curious about water/ methanol injection (has anyone used it and is it safe for a diesel)

Maybe a upgraded cpu from heath or ssdiesel etc... Any ideas? oh and a special thanks to everyone who helped me try and fix my old 87 6.2L...
