<DIV><FONT color=#000000 size=2>Hi guys,</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>Got a guy I'm trying to help out at a
neighboring shop. He's got a customer with an</FONT></DIV>
<DIV><FONT color=#000000 size=2>AWLB Prom (90 GM 5.7L C15 Truck) and the wrong
camshaft. </FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>Right now, the guy has put a Comp Cams 280H
(.480 Int/exh and 280 degrees duration) in his bone stock truck engine, has only
14" vacuum at idle (needless to say his truck is really overfueling). Runs
like crap till around 3000 RPM because of the overfueling. Only other
modification on the truck is headers and a dual exhaust.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>What's the plan of attack to correct this, based
on differing parameters in the PROM ? I realise this is a 16146299 ECM, and I'm
working on an *.ecu for this one right now...but ideas from a 7747 would really
help.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>Thanks--I'd appreciate straight answers and not
things like "he chose the wrong camshaft" <g>. I'll at least
admit I'm not sure how to reduce fuel vs. MAP.</FONT></DIV>
