It should not be too bad a ride up to north Jersey. The guys at TT Performance (TTP) are awesome. They live and breath GM performance and clearly know what they are doing. One of the guys at the shop has an 05 V that dynoed at about 520 rwhp HP (403, all motor) while I was there one day.I don't know if you want to travel out to Jersey but there are a few respectable shops. CARTEK is in Garwood and TTP is in Clifton. Both great shops and great tuners.
You guys were at the NASA event at the end of February at VIR weren't you? I was there in an HPDE, but didn't have time to swing buy your garage to oggle your car.Joe at Phoenix Performance did the tune on our CTS-V race car and we couldn't be happier with the results.
