The only one that can reprogram the 496 computer is Whipple Industries otherwise you have to buy a new one from Mercury

Did they have to pull your motor to do the install?

Re: From Mag to HO

I'm thinking this is the way to go....Maybe pull the heads and have them worked a little put some roller rockers on as well. I'm curious if they had to pull the motors as well would be close to get that cam out over the top of the seat, but looking at it I think it can be done....I have my winter project.... :D

Hey 30OL give me a shout. I think your on PBP you can PM me your # I lost it awhile back and can't get ahold of you on TBM anymore so if you could PM me your # I'd like to chat with you more about the CMI's I still haven't put mine on and am seriously thinking about putting the cam and ECM remap while doing it. It can't be that hard to put a cam in seeing as I'll be doing into it that far I might as well do it all at once.

Has anyone else tried this and seen the same results? I know that the only difference in the 2 motors is the cam and ECM so for that kind of money its definately a bargain. I know the $5000 upgrade when ordering includes the X drive, but the standard bravo will handle 425hp all day long.

Im also looking at this...

Raylar can remap the ecm, their BP102 cam and get 436HP at the crank. You can add their heads and intake later and get at least 500HP.
