i've been searching for chips for my phazer also. Now are you talking about the Fuel "chips" that allow you to change the fuel mapping or do you mean chips to gain power. Found this brand on ebay called genesis that makes chips for all efi sleds and it adds a claimed 25hp. found out it was just a scam which i beleive as you can't really chip a sled like you do to your truck.
i ride where its steep n' deep :P
