I went with Level 2 rated up to 400 hp and 375 ft lbs torque.
Since the purchase and installation, the engine dyno came out at 380 hp and 450 ft lbs of torque. So the torque rating is a little lower than what I'm running. I guees I'll see how it stands up over time.
In hindsight, I'm not sure if I still wouldn't go for the Level 2. The Level 3 is quite a bit more money and my car is primarily a cruiser with the odd squawk off the line.
