Hey all I'm 18 and have been working on and trying to learn about my 1991 K2500. It has a 350 TBI i built last year and a 4L80E that was built a few years back.

Currently I'm trying to decide if it'd be better for me to jump in the rabbit hole and try to learn to tune myself or if I should pay someone more knowledgeable to burn one for me.

I'd like to adjust shift points, lockup, and line pressure on my 4L80. I would like to play with fuel map and make a better more aggressive timing cure as well. This winter I will be swapping my mildly ported stock swirl port heads for a set of heavily ported L89 heads with 2.02 valves, paired with an Edelbrock performer intake with a spacer and a TBI adapter plate.

I know how knowledgeable the people of this forum are and I'm excited to be here. I was referred from members of GMT400.com
