Have a '90 K5 and of course every ^$*&%%$ thing on it is controlled by that computer. This weekend I tried to replace the printed circuit and of course LMC sent me the wrong one. My speedo is controlled by the comp and the circuit they sent me had no circuit for the speedo. The computer limits you so much as to what you can do. I'm also about to install a new engine but you have to compensate for the computer in every thing there as well. I will probably go w/ a 350 w/ the Howell Multi-point injection system. Seems like the best option. I guess what I'm getting at is that the computer is a pain in the a$$. I saw that someone posted a pic of a custom panel last week. I'd love to do that but the comp. wouldn't like it. I have to say I'm jealous of you guys w/ older K5's b/c you can just do whatever you want with your trucks. Have any of you guys w/ newer K5's ditched the computer or do you just live with it. Any advice, help, suggestions, solutions?????? Thanks.
