well they will be happy to know that this will be duplicated and spread among about a dozen performance car forums within the hour that are very popular in the honda, evo, supra, subaru, mustang, nissan, and srt communities. hopefully those scum sucking sons of  will feel a decrease in their business. that is not how you treat a customer. that really pisses me off on your behalf tom. sorry i dont tread water in chevy forums if i can help it. someone else can do that if they want.
I've used treadstone before for oil feed and return lines and flanges and gaskets with no problems. Shouldn't be difficult so screw up small order like that. But hearing a review like this on something very important as turbo specs and they didn't get it right and won't make it right then I won't ever use them again. I don't want to risk ordering another turbo in the future and have it be wrong then deal with incompetence, no thanks.
