My name is Adam and im in Charleston WV. I have a Frankenstein Astro van; 93 body 98 awd frame 94 LO5 93 4l60e 98 borg warner 4472. 3:42 gears mostly everything is factory except the exhaust (open headers) and air cleaner (Edelbrock cheapo). I tuned my 86 olds delta years ago never really had much issues with it (mostly because its speed desity). This TBI 350 is tryin to get the best of me. Every thing seems fine except the AFR's. I can not get it to fuel right. The heavier the load the worse it seems. I put the LO5 injectors in the factory van throttle body because the throttle mechanism is slighty different. I dont see how this could be a problem Im fairly positive the bores are the same. Some one help me out before I slap a quadrajet on it. Or even better a 4bt in it.
