In my experience (I've had motors go on other cars with rod bearing problems) when a rod bearing "fails" it is typically due to detonation or oil problems (heat or starvation or both) and not solely the bearing. You presume oil issue due to not having detonation, how do you know you did not have detonation? Are you running an engine management system that literally logs constantly? Do you have knock sensors on the car? Sometimes detonation is very hard to hear with human ear when you are running hard due to other noises happening especially on modified cars. Not saying your issue wasn't oil caused, but wondering how you know it wasn't detonation.
Please bear in mind it is way, way easier for a tuner/vendor to presume a problem was caused due to an "oil issue" than due to a "tuning issue". One places blame on them, the other does not.
Not saying this is the case again - but I've had vendors pull the "oil issue" card with me, but ended up seeing detonation evidence on tear down. Fortunately I had an independent motor builder do tear down and I inspected the parts and at that point I could cut my losses and move on. Unfortunately, if the same vendor that tunes your motor tears your motor down after destruction and you don't inspect the tear down they can tell you whatever they want.
Just my wonderful experience with aftermarket tuners. I would say even in the very best situation if you or an independent motor builder tears down your destroyed engine one cannot always tell EXACTLY what the culprit was between all the different things that can be working in conjunction with each other to cause an engine to ultimately fail.

I was there for tear down,... I saw the suspect rod and crank, no detonation,....I have, and have had from the beginning a Zeitronix wideband for fail safe /data log/ and general monitoring of systems....... My engine wasn't destroyed,...it was one bearing in one rod.
