You might have mis-understood. Speedlab's tuning service is NOT your 5000km tune up or maintenance job. It is a method of optimizing your engine's performance by adjusting the fuel and ignition system. This is what is normally done to sports and performance oriented cars.

The main problem with auto-lpg installation shops is they cannot tune the auto-lpg kit to run at optimum level. They can get it to run at a competent level and for most purposes, it is satisfactory. But that means there is a margin where improvements can be done by doing fine tuning what is already on the car, including the auto-lpg systems.
