The standard 7.5 boost in Colorado is really 5.5. I'm looking for either a 2 or 4 lb pulley to get the boost closer to 9. My tuner says at 9 the rwhp should be real close to 400. I currently have 351 at 5.5.

Roush does not sell the pulley so I'm trying to locate an aftermarket source. Do you folks know where I can buy the pulley?

Thanks for the help..
