It seems like almost everyone that has this on a revup is doing both. Anyone out there that did this in stages with the Mrev2 first? I've seen the dyno charts and from what I can gather the only real difference is 5whp above 6k RPM, a few more whp in the low end, so I imagine that the noticable difference from adding the Mrev2 is going to be much much larger than when I install finally get around to buying a 5/16th later on. Anyone want to try to convince me to grab both for the install at the same time or do you think I'll be alright just doing the Mrev2 alone first?

I'll hold off until I allocate my money to some other things first!

USE A TORQUE WRENCH!!! Do not wrench this with a socket wrench. You torque it in three stages 40/80/100 INCH/POUNDS. This is very little torque but you must have a TQ wrench so you don't warp something or strip off or snap a bolt. (several have done it on here)
