I have a 40 hp and my dealer said they could up the HP with their computer but he wouldn't do it because he wants to keep in good relationship with LS .I ask my Dealer about that and he said that if they had to replace the computer they had to furnish the S/N and then they get a program to flash that computer only , so a sneak upgrade through your dealer wont work and he said you cant pay for a upgrade hp boost front LS.
Im sure someone is going to have a work around this soon.
