I installed the TRD supercharger on my 99 Taco last December and have put about 5k miles on it. My question is...I hear a high frequency whisle under light acceleration. If I let up on the gas a little, it goes away. If I give it more gas, it is replaced with the rrrrring sound of the blower. Does any body else experience this and if so, is there anything that can be done to silence it????
