Thanks for all the advice! So with the efi...would running the injector plate I linked earlier with 8 injectors and 2 TB's be a feasible option? Not sure what computer setup would be best for that application? Dominator? HP? I have the TB's picked out as well I'll get a link to those

Injector plate

Throttle bodies

Holley EFI 112-587 Universal 4BBL 1000CFM Throttle Body

Thats one way to do it .
or the set up I had that had everything built in, injectors and iac.
There`s a main unit and a slave unit .
HP ECU would be a great choice.

heres the part number i used ..

I have yet to really figure out the knock sensors.
It`s not as easy as it sounds, lots of 'noise' in a marine application, get it wrong , it starts pulling timing and there go your egts and exhaust valves.

I see that holley now offers the terminator in a 2x4 setup which is essentially what you had...wondering if I should just buy that as an upgrade to my sniper and be good enough or change everything to a system like I listed...did you have any issues with the terminator setup?

Holley EFI 550-1075 Holley EFI Terminator X Stealth 4150 2x4 - Black

Are you saying that going to the whipple was not worth it?

Seems like they package the slave and main TB`s together now as a system which is nice, I had no issues . ran like a champ

I couldn't really tell from the pics or description but it almost looks like there is still only one IAC on the system which is dumb lol....Holley has a stand alone addon IAC I can use with the terminator but it just sucks its not built in.

I second wildmans question.....the whipple swap wasn't worth it?
