I am still in the middle of the tank of fuel I got in the car from the dealer. I assume it is 87 octane. I did a little late night testing and tested out the max stall of the torque converter. Based on what I am seeing on the tach, I can't get much more then 2300 rpm stall when I foot brake. I assume it will only get better with better fuel and a tune. For those of you who already have a tune, or have been feeding your EcoBeast 93 octane fuel, what are you seeing as max foot brake stall? I know the engine is rated at 380 ft-lbs of torque, but at what RPM?
It is really hard to not want to start tinkering with the car, but I want to get some baseline passes to ensure it is representative of what the car is capable of from the dealer. I am sure I will go down a familiar path of "drop in filter" => "tune" but then what? I see people going down the exhaust route, but in my experience, with an automatic car the torque converter has the most dramatic impact. Torque converter design has come a long way in the last 20 years.
