How do you guys like yours, and how much did you gain?

Have you had any reliability problems or anything?

I'm planning on getting one soon; probably the AAM.

 

I've had mine in for a few thousand miles now and couldn't be happier I got in on the AAM_GB a long time ago and bought a few extra parts that were not in the kit. I haven't touched it since I inspected it a week after install. I bought new bolts and lock washers for a more secure install and peace of mind. Which is exactly what I have at this point I posted the extra parts in the GB thread...you and find the info there.

I have had the Motordyne spacer installed for a few thousand miles as well. Love it. It seems to be a no-brainer mod. It increased power across the RPM range and noticeably at the high revs. I retightened the center 6 bolts after 1000 miles (just barely) and checked it again the other day--all are tight.

 

wheres the GB thread at? im about get get an AAM spacer as well

 

nice. I'm paranoid and don't want my engine blowing up or anything.
