Yes, that is a bubble in the sidewall. I hit a chunk of something just before I took them off the DSM last fall. It hasn't grown at all, and doesn't cause any vibrations or anything, so I'm gonna let it go for now. If it starts getting worse I'll change it out.

For tuning options, I'm pretty much down to Nistune, or Megasquirt. I've got a spare 5 speed ecu I could send in to get the Nistune chip installed, or whatever they need to do to it. From what I understand, it's reasonably easy to work with, and should support my goals pretty well. For Megasquirt I would need to build an ECU, and I would have no idea where to start for that, or what sensors I would need to make it work.
