Just like the title says, anyone ever deal with TSI out of Addison IL? Was talking to a guy that I know who is HUGE into drag racing and he was telling me about this guy. Every car that he builds gets this guys transmission and he is running some serious HP throught them. He was telling me that the guys is also building diesel trannys now for guys car haulers. I was just curious if anyone has had a transmission done by them and what you think of it. Thanks
