Does anyone know what the max boost on the 600 is if the computer isn't holding it back? It seems to me that a pulley and reprogram would be the way to go. I do like the fact that stock it is now rated for 87 octane. Just need a dual program--one for cruising/trips and one for high octane/boost max power

Without changing the cam you will need more boost for the same horsepower, which will shorten the life of the engine.
There is a reason why Merc uses a different cam on the 700 SCI

Biggest advantage is you can keep your smartcraft computer and the guardian on a 600, even on an upgraded 600 when reprogrammed properly
If you ever used the vessel view or system view Race Edition you do not want to miss all the information anymore
On the 600 the boost is controlled by ECM , so you can reduce boost at cruising RPM which saves fuel and helps your Bravo Drives

Thanks for the info, Dustin and everyone. I've been wanting to know this stuff about the 600sci since it first came out. Looks like it is a pretty good all-around package with aftermarket help

Do you already have a reprogramm for the 600 SCI PCM Module that works with or without a bigger cam and more boost or do you exchange the smartcraft system to a MEFI system like you do on the Mercury Racing 525 EFI Whipple Kit and loose smartcraft monitoring and guardian systems ?
If yes please show some Dyno results

Hey guys,
Just finished testing my PR 42 with Dustin's stage II kit for the 600sci and was blown away. With stage 1 I picked up 4 mph and was expecting maybe another 4 mph with the second stage which would have put me at 108 mph with Bravos...........was I shocked when I saw it hit 111mph in a relatively short distance with 2 aboard! As a matter of fact I didn't even play with the trim and found out it was actually tucked in a bit. With the same 6 blade Hering props I went 100mph stock, 104 Stage I and 111mph Stage II. Dustin's sh*t works!!
