Dynojet(maker of power commander) need Spyders with aftermarket exhaust for testing their ecm tuning modules.
In exchange they will provide you with powervision cx, the ecm tuning module, tuned for your spyder.
I don’t know about f3 or rt but they need RS, hopefully 2013 or later 😊 for a week or so.
I was going to take mine in but I am not in Vegas right now. My old 09 RS was the test subject for power commander.
They are located in north Vegas and you will have to drop it off then pick up.
Pm your email plz if you are interested.
