I've been using Powermaster fuel for awhile now. I originally bought it because a) they make Traxxas Top fuel, and b) it's inexpensive.

Yesterday, I had my Ofna MBX Pro out and I just can't seem to get it tuned correctly. If I lean it out it doesn't like to idle, at 3 turns (HSN) it idles real good but boggs when you really give it fuel.

I'm wondering now if it's the fuel?
