I’ll just mention this since it may not be apparent. Boost with a centrifugal supercharger, like the one in this kit, is directly related to RPMs. Boost rises in a linear fashion as revs increase. With a “15 psi pulley” you will only hit maximum boost at redline, typically 7500 RPM. So you may for example only be at 12 PSI at 6500 RPM. So you can control boost by controlling RPM and shifting early.

It sounds like you would have 2 maps. One with meth injection and one without. You could just get a high boost pulley and then have your non meth tune with a redline of say 6500, which would keep your boost below max. Your meth tune would rev to 7500 and give you full boost. No other form of boost control needed.

These number are theoretical examples, not actual real world numbers.
