I drive a Mazda 3 MPS (Mazdaspeed 3 elsewhere) and found 2 irritating behaviours of the car. First, whilst on boost the engine would tug the car a bit and 2nd the manual box was mushy and not as precise as I am used to. After some research I fixed the mushy gearbox by changing the rubber bushings that mount the gear stick in the car to metal, and replaced the rear engine mount with a stiffer stronger mount that limited engine block bounce. The gear changes are now much snappier and I have the added benefit of less axle tramping under load. A double win! As for the tugging on boost, it seems the stock recirculating BOV is a bit leaky. I have not changed that yet but have driven another MPS with a different BOV and the difference is marked. Better yet it does not go PSSSHHHHT! My mother of all people commented last weekend “Wouldn’t the manufactures have put the best in there?” Cant blame her really, she is lucky enough to have 2 sons that will drive 2+ hrs to service her car ? .
