yes, I do...I'm still getting use to my new AEM interface though...done reflashes/accessport...hydra, I've done a little despite coming from a certified hydra tuning shop. Link 44s and PE are what I'm most familiar with. UTEC sucks but I've spent plenty of time on that too.
I also tune meth cars which a lot of people don't. I just require having an EGT.

As for motor builds, I've never had an issue with any of mine. Now I'm doing something kinda crazy on my own personal build. I'll share that later though.
