Attention Auto Geniuses, Nairb Is About To Lose It!!! Help!!!

Guys,

I replaced the engine on a 1995 Mazda Melinia S. The engine is a 2.3 Millercycle with a lysholm screw type supercharger.

The engine will run and idle fine, but will not rev above 1500 RPM even if you hold it wide open.

This particular engine has a dual intake manifold system similar to a Ford 3.8/4.2, in that it switches a valve when you gun it to allow the supercharger to do it's thing.

I have checked exhaust backpressure, and fuel pressure. All within specs. The engine runs just the same with the exhaust removed so no plugged exhaust.

I need information if anyone knows where to get it. Desperate for help!
