Default Really sick bonnie

As you've probibly figured out, I'm new. Anyways I have a 93 SSEi with alot of motor mods and i don't know what to do to make this thing work. basically its the bonnies just got her original block and heads all the inners are Grand National (Crank, rods, pistons) Its got a 540 lift camshaft in it. The heads are hevily ported and they have over sized valves,roller rockers, cromoly pushrods fully adjustable valvetrain. Its got the stock blower but i custom made a blower pully its 1and a half inches diamiter (The snout of the blower is bigger *LOL*) Its also got a freeflow exaust and the big Grand National injectors. I've done nothing with the computer. i think the wastegate on the blower needs adjusting to try to make more boost. All this and its no better than a bone stock one. I just don't know what to do. Any ideas or advise would be greatly apperishiated
Thanks

It sounds to me like a "Customized Chip" may be needed next!

Compared to Ford and Chrysler ECMs, the GM one'* are dumb as nails.

If you've got the GN around that you used as a donor car, then I would just use the electronics from that, and swap wiring harnesses. That way you've straight up got a GN engine setup just using a blower instead of a Turbo.

Or you could just keep the GN.

Because there is alot more custom support for the Gn you will find using a gn or gn compatible computer is the wise way to go. I would also see about setting up a centrifugal SC instead it would give the engine a chance to show its real potential. Go to zz performance tell them you need to talk to zoomer then tell zoomer domestic performance sent you. Tell him you are in need of some help he will help and can provide the definitive answer. He is also the exclusive ISP centrifugal sc provider. Excellent unit. If zoomer can not help I suggest talking with DHP they can also tell then I sent you actually one of the people on this site are connected quite closely to DHP. Oh and the last and maybe the first place to talk to because they work with both gn 3.8 and Bonneville 3.8l engines is Thrasher. All these companies are easy to find on google or the link section of this site or my site.

But he had to take it off the road cause of inspection and emmisions ! And that'* n/a !
