Sniper EFI or stick with carb?

With O2 sensors and good ignition, you can tune a carb to operate almost as well as efi. I am also sniper curious but the Inovate wide band has allowed me to get everything so tight, I don’t want to F with it. I’m going to vote for a good wide band set up and four corner jetting and go wring these things out already. It’s mid April man!

I agree never ever get a fuel injection system that has to have a correctly functioning O2 sensor all the time.

I suspected some of the issues were installation related. Some of the pics I saw of installs (boat-wise) were far from what any of us would do to test things
And I have no problem with over building electrical and fuel supply.
I think I’m pretty much convinced.
Is the 650 hp version (four injectors) enough for my 509? I don’t plan on building beyond what I have now; similar 9.5 AFR equipment builds are in the 625 range. For head room I can pickup the next level that gives another 600 hp of room to grow (lol), but I’d rather spend the money on the pumps and routing (better money spent).

I had my QF850 really dialed in using an AFR gauge, but when I did the rebuild I really didn’t feel like ****ing with that thing again. I still have less than five hours on the Sniper setup on a completely different beast so can’t say too much about it other than I love not pulling fuel bowls out in the middle of the lake or waiting until I get home to do anything.

cleaning out internals and new gaskets and maybe needle/seat and acc pump diaphragm unless a real ratty carb which of course yours was not.
