I just couldn't wait till the off season to redo my efi system. I ordered the new Holley HP efi controller from Haxby. It is a self learning unit. Then I went ahead and ordered the 71 lb. Injectors from RC injection in California. I have already upgraded fuel lines, filter head, etc.
I think I should have a nice piece once I install these last few things.

Keep your eyes open for a couple of Boost referenced regulators soon to be listed in the Swap Shop!

Thanks for everyones help on this !!!!!

Give us feed back on how things went. I earnestly hope we steered you in the right direction.

Injectors arrived today. Looks like they should drop in no problem. I may have to do some minor Die grinding on #1 and #8 on the intake manifold because of the Injectors slightly larger diameter.
I really like the way Eddie Young mounts the electronics on a carbon fiber plate on the back of the motor. I wanted to do something like that with my Holley HP,but I am very limited on space back there so I am going to mount mine on the Port header where the stock ECU was mounted. I do not have any real carbon fiber on hand but do have plenty of 3/16 aluminum plate and carbon fiber replica "formica" so I am going to fab up a fake carbon fiber mount.

Fuel pressure regulator mounted on its own "carbon fiber" plate.
I have been having great luck with this old Lightning header that I welded a bung into.
Also RC Injection flowed the injectors before shipping and included print out. I should be back on the water soon as my Holley HP system arrives.

Holley HP arrived today. Time to get to work and get this thing back on the water.

interested to see how user friendly that setup actually is..good luck Rob

Cool deal Hadley, good luck and im looking forward to hearing what the Holley efi is like.

Thanks guys, Installed new injectors tonite and removed old wiring harness. Holley system looks pretty nice so far. Just started a bit of wiring.

Took the boat out yesterday for the first run with the Holley HP system and larger 71 lb. injectors. Runs awesome!!
Datalogged the run and my A/F was spot on throughout the entire RPM range. Alex Haxby emailed me a base tune that worked awesome.
Install and set-up was very easy even for a Fuel Injection amateur like myself.

Awesome to hear, your carbon panel looks killer !
