i dont know about that statement anymore. i have the unlimited and i think its streetable. It could just be a hit or miss from what ive heard. If you buy a used one, id send it back to chip and have him look at it (its free). I think his new software or what ever he does to them makes them a little more streetable. It does have a little stuble when it takes over but after that i can run through any rpm range and have no problem. Mines even been working and not setting off the check engine light.
