Re: TBI ??

buring a prom (new computer chip) for the modifications you have made, if everything else is fine possibly a fuel pressure regulator??? someone knowledgable about fuel would have to comment on that idea, but PROM is the main thing with this issue

Correct. With any cam swap chip work is needed. Without you won't be able to band aid the set-up enough to where it will run like it should. Fear not, there is plenty of info on this site to help walk you through the process.
