Ive thought about that to. I think i might throw on the bully dog from bikeman since i have all thier parts on anyways so i can inject more oil and then run a wide band a/f gauge so i can still tweak the tune thru the powercomander if i want
I put the bikeman head on after i had the bikeman pipe on and i can honestly say i felt alot of midrange trq and a couple more mph on the top end gained to.
I took my t stat out of my stock rush. Runs way cooler. I also don't run a t stat in my Switchback with bikeman head. I did notice more mid range pull with the head.
Silber turbos I don't think fit the pro s/x bulk head. At least I know the boondocker kit doesnt. Silber won't answer me back on...
