Unfortunately the do not upgrade the silver evos anymore. Nothing having to do with the trucks, just the programmers, more specifically the cable.

Were you running the trans only or performance tunes?

i was running performance tune with 93 octane

Try running the tow tune. It is designed to run a bit richer and will help offset the lean condition.
