Knock sensors do come in handy at times so for me it's better to be over safe then ever sorry.

I understand about the versitility but lack of flexibility with the MS. For me it's just that the aem ems can do so much more and offer more control, is proven and money wasn't a factor so it's the right choice for me.

BTW - CFT has aem ems for sale at like $1200 right now brand new and microtechs at like $800. Incase you are looking to buy soon slash.

I'm hoping boostjunkie will jump in here when he see's this since he has alot more hands on experience and a wider range of stand alones he has worked with so he can give better information then me since im still in the very early stages of stand alones and capabilities and so forth when comparing.
