spools way faster. the 9180 out spools that charger. hands down. i just picked up a steed speed t4 manifold for a cummins and im gonna throw one of the two on my buddies truck. He wants one. i figured these would be sold by now. looks like im posting them up in a subaru forum haha
Have you tried one? My charger lights just as fast as the efr as you're describing.
