I have been storing parts for when it gets warmer, so I can start playing with my gmc. I have all kinds of tbi stuff in parts and alot of files pertaining to the regulator modification to make it adjustable. Every thing out there states that this is done on your own, but it doesn't really state when stuff like this is needed. I'm also got an exhaust in parts in the garage too. headers (from a buddy's International Harvester with a 350) a couple of 2.5" in and out glass packs, but now cat.

So when do I actually need the regulator to be adjustable, after I install the spacer plate? Or after I do the exhaust with the spacer plate?

I do have the dodge as a backup DD, I wouldn't dream of playing with the computer, motor stuff and not know what it will do to the daily use of the system
