Yeah... you need the $1100 injectors on your n54 no matter what. These aren't secondary injectors.
VPG 777 WHP DI ONLY

I don't see how you can add the factory injectors as an issue since you don't get rid of them with port and, I also don't see where the $700 hpfp is part of the equation either since the kit is covered in the first line. do you just have something against using DI or are you pissed that the PI you probably have already just became unnecessary?
He had to replace 2 during testing as it magnifies any potential issues
Whether you factor it in or not I do.
Since the kit is covered? What does that mean? I'm actually in the market for secondary fueling and that was the add on in the drop down menu on the VTT website
I'm actually pricing kits out to make a purchase. How about you?
Something against DI? PI unnecessary? You're coming off like a DB and that's not double barrell
the kit being the double barrel kit you put on your first line. that covers an HPFP right there. "$1200DB vs $900 rail" there's no need to factor a second one in right after that. I'm trying to see how you're trying to talk this down like it's a waste of money. there's gotta be a reason for your saltiness towards it
No it does not. It's also going to be a factor servicing the kit. Having replaced everything on this car twice over already I always factor in cost of components after failure. That goes for part cost and how much of my time it will take to actually replace. My OEM hpfp is very easy to swap and I need to see how easy this one will be to access when it's time to replace.
If all things DB vs PI were equal or at least near equal he would own this market share. Do I think the margin has to be cut relative to where the market is now, yes. It has to make sense to me as a consumer. I'm a part of this market, money in hand, ready to spend.
There is zero saltiness, I know what kind of effort the Vargas team put in to developing something like this. The N54 platform was stagnant until he showed up. I've purchased from him before and would not hesitate to do it again.

Shit, I just assumed for that price point it would include the pump and didn't bother looking further. I'm gonna have to agree that there is some margin that could be cut but I guess there has to be competition to make that happen. I'd still go with the DB over PI for my own car but I'm not going to need that until maybe next year unless these stock turbos fail quicker than that and force me into GCs quicker
Great numbers VTT team. I'm glad to see progress on this design. It just makes so much more sense than Port Injection.
I was wanting the details on pricing, product launch, and availability on the SS controller that is modified, DB kit, and possible LPFP pricing since you have developed one. I understand the shotgun product that has been out for 2.5 years. Not needing details on that. I visited your website this morning and your fueling products were not listed. It appears since then you have updated the website. I will specify the details that I am requesting next time. Look forward to seeing more of these on cars to understand the reliability on the street and track.
Could this be run "along" with PI for those attempting to push 1K WHP? With either stage 4 lpfp pump on the market now?
The newest hpfp hasn't seen too many failures that I know of (13517616170). You can find them for approx. $500 new if you shop around. Some of the older revisions can be found for $200 and less.
One thing to consider is the DME failsafes are still in charge using the rail pressure sensor, and also still in full control of the injectors. Big plus. Timing will always look a lot cleaner as well using DFI.
The install looks a bit of a pain for the guys that wrench on their cars but am curious as to how easy it is to access the secondary pump once it is fitted when wanting to swap it.
Tony is probably already working on modified injectors to make PI a thing of the past. This is exactly where this platform needs to head, but fml that damn sticker shock.
Tony shared a LPFP surge tank build he had done awhile back. He basically laid out the entire set up and did all of the thinking for us. I'll assume that is on this car but it is way beyond the PnP kits available with a low total budget. Requires work is all.
Wow so the injectors are totally fine as-is (and there is potentially even MORE room there if ever needed?)
Was purely a secondary HPFP control+LPFP flow issue?
Is the SS controller map to be sold/given when buying a double barrel kit?
Sorry, but no one is going to be modifying these injectors. Once they are maxed at 3600psi (whatever WHP that ends up), the only other option for more fuel DI only will be increasing injection window.
This - how many motors have been grenaded due to an injector cutting out and PI still going? There is a cost to account for that risk.
I wonder what happens when you suddenly enter limp mode, how long does the PI keep spraying?
