>new Subaru WRX Turbo....he changed the exhaust >and installed a boost controller it dynoed at 305hp? >Is that possiable? No, not at all. Those things put down less than 200 to all 4 wheels. Without a chip they can't even raise the boost without getting fuel cut. A chip wasn't mentioned at all. He may have gotten 35HP from the mods, but not 305HP. The stock turbo and injectors cannot support that HP level. -Jay
