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.

Danm! ;D no 3" piping ;D 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 >:D

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 ;D 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 ;D 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 ;D




hey 90dx :) whats you opinion on the best way to get extra gas to the engine? i praised you above, thanks for the awesome link ;D , but if thanks isnt enough, heres something i did for you and the other peeps that helped me out ;D and are continuing to help me out :y

would installing a bigger fuel pump alone, get the job done?

Re: 1991 gmc jimmy 2 door v6 4.3L twin turbo help!
 

no
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

you need to modify your harness to work with the standalone, youll need to get bigger injectors.

Re: 1991 gmc jimmy 2 door v6 4.3L twin turbo help!
 

if i get bigger injectors doesnt that mean i got to change my ecu?
or would megasquirt take care of that?

Re: 1991 gmc jimmy 2 door v6 4.3L twin turbo help!
 

Is your truck TBI throttle body injected or is it multi port with fuel rails and 6 injectors?
