Always dyno (custom tune the car ) ,especially if you have pwr. mods like a supercharger.DO NOT ORDER A CUSTOM CHIP THRU THE MAIL! i HAVE BURNED 3 MOTORS BY NOT DOING THINGS RIGHT. And your custom tune should take as many runs as needed to properly tune the car....thers is ,or should not be alimited no. of runs to cut a chip. My first dyno took 17 chips to get it right.. My last motor was pulling 485 rwhp till it blew..plus an advance module in my chip that I controlled for an additional 4 degrees of advance, good enough for 40 more rwhp. you need to add Torco Fuel Accellator to boos the octane to at least 102 to handel the advance. I carry a case around with me. I repeat always custom tune with major pwr. mods........
