Suzuki LTR 450

The stock mapping is not adequate for the Sparks Racing exhaust system.

The small plug marketed by several companies actually switches to a secondary map installed by Suzuki. It is safe to run your Suzuki on this setting, although it does not provide maximum power gains.

The DynoJet Power Commander works awesome on the Suzuki LTR 450. There is a map available.

The Sparks Fuel Management Module by Dyantek also works awesome and comes preloaded with the correct mapping for the Sparks Racing exhaust system.
