Hi, Have now installed a grooved tbi blocked pcv reruted to air filter, blocked all vacum lines on tbi exept for map or is it called maf electric vacum controled air flow sensor, the iac has been minimiced , This chevy 7.5 1985 used to have a carburator. it now has the tbi from a 1990 chevi ss10 , It uses the same amaunt of petrol as the carb did. New mpg will be informed in may, it used to use 33liter to 100km, it ways aout 7 tones, I used metall epoxy to minimice iac and to beable to do a longer groove. The ecu conditioning will be done in may aswell, its parked in storage , minus 10 degres c here today, This tbi wasnt the easyest to groove but im pleaced with my work. Now lets see those picture, over and out for now, with love from me.
