Well, the MSP comes set at a fatory 5psi. At a Mazda Rev It Up event I talked to a major Mazda tuning guy and he said they've boosted them to 15psi on stock internals. Just some tuning required. He stated that its gonna make a blast into the aftermarket real soon and once people are going to realize how potent they are capable of being, it'll be the next SRT-4.

I guess that explains why its only rated at 170 chp from factory.

I would most certainly sport a MSP...in black or grey. Maybe yellow :rick:
