Alrighr, so i know the 4.3 isnt worth building or putting power behind, but how can i put a new tune on the ecu.
I got an exhaust done because i think the motor sounds great, qnd somewhat expected it's runs stupid rich. Like i spit fuel out the exhaust rich. I know i could do the whole eprom adapter thing to be able to tune it, but it just isnt worth the price. Is there a good chip, or some other way that i could tune the car, so i burn less rich, and maybe get a little power out of the exhaust i got done?
