What a tour limiter? and be careful with gas around fuel(petrol), The car will blow up!

I don't quite understand what you're asking about I assume English isn't your first language.

if you have a -31 actuator you'd be best getting the ECU chipped to match. Keep an eye out for a white/red/blue ECU without the Knock sensor with a chip and get a tuner that knows about Bosch K/KE Jetronic to set the car up.
