Is there anyone in the GTA or in the london area that tunes the rtek 2.1 system?

 

I've got one. I played with it a bit. They are really easy and straight forward to use. I'll probably end up tuning my own once I have the car together.

 

no one in the GTA or london area who tunes them?

 

Anyone who does tuning should be able to tune it for you. They are a pretty simple and easy to use system. No where near the complexity of other systems that are available. A quick read through the user manual and you pretty much have it.
