Re: engine tuneing

Can I ask why you would switch it from FI to Carbs?

Re: engine tuneing

Can I ask why you posted this as a Poll?

Do you know how to tune a carb? Are you boosting this engine? I could be wrong but i swear ive seen chiping kits for those 4.3's using like tunerpro r/t or something....

Re: engine tuneing

im hoping this isnt for turbo...if it is, perhaps consider switching from tbi to a normal fuel injected setup off a newer 4.3 (im not sure how easy/hard that is). Otherwise, im betting you would need: intake mani, carb, low pressure fuel pump/regulator, and a new fuel line setup
