I guess when you don't crash and think that your times could be faster with the extra speed.

Adding boost of turbo can be beneficial, or it can be totally counter productive if you don't understand the speedo settings and how its applied. sometimes you will be fighting the boosts an turbo coming in and out which will either give the car a kick in the corners or totally unsettle the car.

With boost, if you set it to come in at a lower RPM point, the boost is spread across the entire rpm range and so feels more subtle, but it will give you some extra. The amount you are comfortable with need testing. if you set it to come in at too high an RPM point, you'll feel the step as the boost comes in, which can/will affect smoothness. This can be counter productive, and can affect your driving. Experiment with the amount, add 10, then 15, 20, etc, and watch your temperature.

Turbo for the straight can be useful for that extra when you are at full throttle. The critical bit is the delay, which controls when the turbo timing is applied. Too low a delay and you get a much quicker surge coming in when you just touch full throttle. Too long a delay and it will come in too late on the straight, so you've more work to do to show the car into the corner as the speed is still ramping up. again test it.

Actually sometimes the keeping the speedo on blinky with no timing or boost and changing the motor to the track is the best approach. If you are struggling with your speedo settings or complexity, just buy a new lower wind motor ;-)
