Message	I opened up a pair of stock TBs to 54mm. I machined new throttle plates out of stainless steel with a 7 degree taper to seal properly. I still need to flow test these against a stock TB but I expect decent gains in CFM. If it looks promising I will start producing these and selling them on a core-exchange basis.
