I findly got around to modding a 'round MAS' ... Have had info in my head and on paper on how they really work for some time now... Just no time to RnD the mod .. Did some rework on the circuit board to up the fuel ... Get lots more air into the motor around the MAS ... But the MAS seems to keep fueling and not going looney over the bypass of the air .. One problem with GEN1 EFI as HP goes is the MAS plugs up the intake track ... I'm at a point where the TB is now the problem ... Have a 'almost' bolt on TB that ups the TB square MM by 30 plus over stock thats nexted ... Anyone have a 89 upper intake ...?
