Why wouldn't this work on a naturally aspirated engine? They make a kit for naturally aspirated engines. I know that the gains wouldn't be 88 hp and 100 torque but wouldn't the gains still be good on our 3.7's?
These do work on NA motors, but the effect isn't nearly as dramatic as on FI motors. I guess you could run a 100 octane tune, but not sure how much more power that would give you. I'd rather go with gears.
