Just installed an Edelbrock E-Force S/C on my 06 GT. I am running an 3.875" pulley (entry level) on the blower. From a stop going thru 1-2, it seems to have some belt slip and boost loss. It's not even at full throttle. Damn belt keeps slipping! What would be the best tensioner for my application? Would thisd solve this problem? Does anyone else run into this problem?
