I would have the dyno shop adjust your tune to adjust your air fuel ratio. only takes a moment and ive read some posts where long tubes do you no good.. they are wrong. I gained 30 ft lbs of torque and 16 horsepower and that is after a 25 degree jump in temperature. you wont recieve a gain until you get your a/f adjusted properly. on mine I had to raise the wot fuel an additional 5% both on 2k-4k and 4k-7k. good luck.

that stinks if you didnt get a gain from the long tubes. thats a lot of cash to put out for notgetting a gain in Hp. I stand corrected.I would think that with a supercharger the gain would even be greater
