I am in the process of trying to tune a turbo 1999 4.8 80e in a 92 Sonoma. I have tuned one turbo ls in the past and didn't seem to have this much difficulty. My problem is that after licensing and applying the 2 bar enhancement I have no fuel table past 105Kpa. I'm using a turbo 4.8 tune file I have saved from my previous turbo build. Also, under the OS tab nothing comes up(blank). I've read through the forum and cant seem to figure it out and I'm getting frustrated. I know there's a lot wrong with the tune as I just started and was going to start in the fuel table. Here's where i'm at.... Thank you, Jase I'm also a newbie and not a computer wiz so speak slowly..ha
