WITH gm tbi?

i am running a weber 32/36 currently and have had the wire harness made and the throttle body rebuilt for almost 9 months. never got the adapter plate or fuel pump...mostly becuase i had put the 4.0 head back on and found out the **** chip needs to be tuned in the computer for w/e mods you have. so i have been holding off because of that and doing all the other upgrades 1st. i just don't wanna spend the money to get the chip reprogrammed.

thanks for any/all suggestions!
