A little clarity. Yes, I was speaking from going from my old 3-blade to a new 4-blade. That was my intent....and thats where I WANTED MY reply to go..my opinion..period! I overstepped talking about the NEW 3-blades because to ME they were not even a option for me. I wanted the BEST not middle of the road gains-(my opinion) The 4-Blade was the LAST big upgrade I did and it should of been the 1st thing I did. THE GAINS WERE SO INCREDIBLE!!! It was like putting a SUPERCHARGER on my engine and I want to share that with yall. I wasted so much time and so much gas and wear and tear on my engine. Lets keep this REAL simple..call your supra dealer and ask him which new model comes with a shiny new 3-Blade?? NONE!! Period!!
