Large tracks may require an extra 0.10mm shim to reach higher top speed and improved fuel consumption, but this will decrease acceleration slightly.

TURBO COLD GLOW-PLUGS to use when humidity is below 70%
•P5TC hot filament
•P6TC medium filament
•P7TC cold filament

TURBO HOT GLOW-PLUGS to use when humidity is above 70%
•P5TH hot filament
•P6TH medium filament
•P7TH cold filament

The filament number will depend on the ambient temperature. Colder use hoter filament. Hotter use colder filament.
