RIOT - sorry to hear you're going through this; big "thumbs-up" to EC for supplying you with a replacement motor.

When convenient, I think it would be helpful for the forum if you were to chronicle your mods in some sort of orderly fashion. Something like:

"A" intake installed xx,xxx miles and xx months ago
"B" pulley installed xx,xxx miles and xx months ago
"C" tune installed xx,xxx miles and xx months ago
"B" pulley removed, "D" pulley installed x,xxx miles and x months ago
"C" tune revised/updated x,xxx miles and x months ago

etc, etc.

Obviously, I have no idea of what your mod-path has looked like - many others might not know either. I'd encourage for it to be as succinct and factual as possible - people can then better form educated guesses on what might've contributed to your failure.
