I haven't noted any of the trans problems as stated by the OP, or by others afterwards.
Should I be counting my blessings at that? IDK
Been run'n the LMS Stage 4 tune for a few months now, if not longer.
But then again, I don't drive it like I stole it. Well at least not all of the time. Occassional "spirited" driving is had, but I don't beat on her by any means.
Also been strictly religious on the 93 Octane....
Interesting reading on the fuel mixture(s) / combo octane booster and what not to do etc....
Perhaps Rick (or anyone else with knowledge on that issue alone) would be inclined to create a separate thread on that topic (so as not to jack the OP's thread here to much).
I never knew about the entire "don't add octane boost" to the fuel of newer engines was an issue.
Standing by.....
