Undefeated

Yes I’ve read that too.. this is new stuff so we are all on the ground floor.. 
 
this isn’t the McGee injection we tried ( my older brother tried that stuff) on in the 80s, as Steve Morris stated “ this IS Holleys  carb replacement!”

From what I’ve read I’d rather the Holley sniper over the Fitech and if I ever went that way with the XD I’d go for their basic 4 barrel set up.

I think the most common complaint is people having rpm noise or similar with leads and things being to close to the ecu, but a well planned layout should sort that.

I’ll be watching. 🤟

I agree with what Greg has said, but I also say do it.
And the argument for getting this rather than paying someone to tune a carb is the same as having programmable ignition rather than getting a re-graphed dizzy (i.e. you change something and you don't need to pay again). It also means you don't need to take it somewhere and talk to someone, haha.
That last vid it goes pretty lean on transition though.

How much boost can these things handle? 

Some interesting comments there deandx.  Has he ever tried a four barrel east wested?  
Gerg - once again you are all over it. 
Undefeated - I've done self tuning efi, albeit with the crude MSD (a Holley Brand) Atomic system.  I swore I'd never do another one as the 'self learning' in that system was pure garbage. The algorithms they had were way off for the i6. Yes things may have improved, particularly with the Holley sniper ecu as a trained user can get in there and change parameters.  But realistically why would you bother with the expense. It amazes me that people would happily lay down $1500+ dollars on a 'self learning' ecu but they wouldn't spend $450 for 2 hours of dyno tuning by a competent operator. Its just mental to me.  
I recently sent my customer to Zoran @ Zox performance in Brissy to have the tune cleaned up because I couldn't make it down there for some time. He paid $450 for the dyno time and he agrees that it's the best money he has ever spent.  Zoran only had to go down 1 jet size from base but was able to trim the ignition curve etc etc.  The car is now a jet and won't need to be touched. 
But hey - if you want to do it - do it.  I'm just offering my experience and advice.  The choice is yours.  
 

I'll butt in as have a couple of points to add:

I guess it comes down to what the EFI system is happy doing; whether or not the engine's requirements are outside the capabilities of the system.

Example: a low vac/high throttle opening at ldle (typical of a radical cam) might upset the computer because it sees it as load. Also, the computer only knows how much oxygen is in the exhaust. If there is incomplete combustion (again with the radical cam), the oxygen content in the exhaust gas will be high and thus, thinking it's lean, the computer will (mistakenly) give it more fuel. Think of what happens when someone installs a high-overlap cam into a MAP controlled E-series engine. It goes a bit haywire.

The concept of the self-tune function rides entirely on the ability of the O2 sensor to read what the exhaust is doing. It may well be that a MAP-controlled, closed-loop system is unsuitable for race applications. The makers of the EFI have to make certain assumptions about what it's being bolted to and tune accordingly, whereas a big dumb old carby just does what you tell it to do no matter what, albeit with much trial-and-error to get there.

Carbies require a lot of experience to get running right, but once dialled in, do an amazing job for what they are. EFI tries to do all the thinking for you, but sometimes it can be a bit too smart for its own good.

This is a bit of a blanket statement, but I think that on a milder engine, I think it would be great. However in some scenarios (particularly idle and cruise) on an engine over 1 horse per cube, self-learning EFI may be of no advantage, even detrimental.

There’s something about triple carbs that just looks exotic..special..
they took the e49 charger with triple carbs to Italy and the Italians loved it..
 
The english e type jags, Ferrari , Aston’s, and others ran multiple carbs set up.. it’s porn..
from a aesthetic point of view it art..
 
I hope you do go down this route..just so I can check out the pics..

I do like the pewter colour... Not as full-on as gold but distinctive from plain silver

I have posted this because I think this is a good option for the ESP and Grand Prix guys ,  who might want a option on something a little bigger whilst still being respectful’? or  anybody looking for something a little classy and unique ? 
 
17”.... old school cool!

I have used 2 aerpro fascias, one uspide down and back to front.
I also reshaped the heater box by cutting out the hump in the middle and will be fixing in a right angle plate to give something to mount the back to.
