I've personally talked with Sean from Vigilant Motorsports, and he's a real good guy and definitely knows his stuff. He's helped me out quite a bit with my 04 rex that I had. And I've seen some of the motors he's built, and they are beasts. He doesn't do the tuning himself, I forget the other guys name, but I'm looking at going through Vigilant for tuning and upgrades once I'm back stateside. I'm also subscribing cause I wanna hear about Half Crazed and his experiences with ET tuning, since I'm not far from them either.
