Summary

00:00 - Alastair's asked, is it logical to tune a completely stock car? It really depends on the car.
00:07 In most instances I would say yes.
00:10 It's surprising often how much the factory tune leaves on the table in terms of power and torque.
00:18 There's a variety of reasons for this, often a single model of car is going to be designed to go all around the world to various markets where it may need to run in very dramatically different atmospheric conditions and also run on very different grades of fuel.
00:32 What this means is that the base map that the calibration engineers provide is often really detuned to allow it to be safe in all of these different applications.
00:42 In our application though, we can optimise our tune for exactly the conditions we're operating on, exactly the fuel that we're operating on and quite often there can be pretty significant gains, it's not uncommon to see gains of 20, maybe 25 horsepower at the wheels in some cars.
01:00 I will add a caveat here, in some late model cars, it's very difficult if not impossible to see any gains so this is where it comes down to your particular model.
01:11 Of course often we're not going to be performing just tuning changes, often we're also going to be performing hardware changes such as improving the intake system, the exhaust system on the car, freeing up the airflow through the engine and then we can see further improvements by taking advantage of those in our tuning.
