Ramblings from a recent install of the track tune......running a cold air intake and 3" B&B cat back with resonator (no cones).....it's breaking the stock tires loose when it hits 4500 RPM. I love this VEEEEE. Big thanks to Stealth for the tune. And more thanks to Reed for hosting and making it painless for us! Not to mention the hardwire on the Valentine. Support this guy on the FAQ site. He's great!
