Re: 1991 gmc jimmy 2 door v6 4.3L twin turbo help!
Here is a third gen Fbody board that has a couple forums on DIY engine managment for GM.I don't know much about it myself but if you start reading the stickies at the top of the forums it will give you the basics before you start asking questions.

you HAVE to have some extra gas into the engine some how. just running ti stock will not work.

no 3" piping ill take your advice and go with the 2", i guess ill use all the 2.5" tubing i bought for the exhaust.. or maybe return it, and get 2" for the turbo and 3" for the exhaust 
in your opinion, whats the most feasable way to get the extra gas?
in both an economical, and effectiveness/performance stance...
using the awesome links 90dx provided me
i was thinking about the megasquirt, but then i came across http://www.bigstuff3.com/and bigstuff3 is a local company... so im kinda leaning towards them
too bad they dont list prices on the website 
i guess ill have to call them up first thing monday, and find out if they can help with the install, and getting me started on tuning

a bigger pump wont do much but supply enough fuel to the rail and barely chande the fuel psi anyways
u need either big injectors/management, fmu, extra injectors...just pick a fuel option and if u tune it right u should be fine
