I am going to have Doug over at Dynamic Tuning Solutions (DTS) tune my 09 V soon.
They are located in Reseda, CA which is off the 101 fwy.
Give em a call.
You will be very pleased with the results. I had "others" tune my previous vehicles and feel that Doug is an all around better, more experienced tuner, not to mention an awesome guy to chat with.
Hit em up! You will be very pleased with the results.
