Do you use it often enough to feel that it was/is worth it? Specialty Z is tuning my car in Delaware November 16 and I can't decide if I want to get the race tune also. It's around $300 between the fuel and the time to the dyno shop and specialty Z. Then if you want the switch to remotely change between them its another $320 installed. Thoughts?
