Thanks for the reply Longshot!!! I'm for sure looking at doing either the e-fans or pulleys for now, and possibly down the road ending up with both mods

Now I've also read that doing BOTH the e-fans and pulleys can cause issues. Not exactly sure what issues, maybe altenator?? Has anyone heard of issues with doing both?? I would love to hear some feedback on those that have done both mods!!! It's nice to now that doing either or both of these mods won't require any adjustments to my custom tunes, which means I can go ahead and get that Gryphon ordered!!!
And I almost forgot, how hard are aftermarket performance pulleys to install?? Something I can do in my driveway with a little bit of knowledge?? Any particular brand you guys would reccomend??
Thanks!!!!
