I have a radix with a 3.1 pulley making 7 pounds of boost. If I put a 2.8 pulley is it going to be safe for the engine (LQ9).there is an intercooler. will i need another dyno tune. Is it going to make too much heat. How much boost will I be at with a 2.8 pulley. does anyone know somewhere in socal to get a methanol kit installed,cost andhow does meth work. does it only kick in at WOT. . . HELP PLEASE
