Simple tuning for your Derbi bike.
The fine and rare Derbi Mulhacén suffers from the same (too) lean air fuel mixture as all other modern fuel injected motorcycles.
With the BoosterPlug fuel injection tuning you get the small, controlled fuel enrichment your Derbi needs to run like it should have from the factory - all in a small package that easy to install with the original connectors (No wire cutting and splicing).

Plug-and play aftermarket optimization part. Before the first BoosterPlug was launched in 2009, the only real fuel injection tuning solution was to install a Power Commander or similar mustiadjustable aftermarket parts, but it was actually not a very good solution, because the PoverCommander is very hard to set up correct with all the different features.
The BoosterPlug gives you the slightly richer mixture where your bike needs it the most, without increasing the fuel consumption unnecessary - and it is quick and easy to install, without the need for extensive and expensive Dyno test bench sessions. This is how all aftermarket tuning parts should be made !
