My friend that owns a turbo place test drove the new silverados last weekend. He is ordering a 5.3L short bed 4x4 to make a TT street terror and start turbo development. So, yes it does start there.

Worst case they cast a new housing specifically for the vette. You should call them about c6 kits. Kevin was asking about them and I told them to get ahold of you.

RedLine Motor Sports is working on a twin turbo system for the C7 Corvette. I know they have allready played with the new computer and have a few dealers set-up to sell and install these units when they are released. Redline has a C7 on order and will use their ride as the mule for this new system...My understanding is it is similiar to The APS C6 but with larger tubo's and different plumbing. The real trick is to get into and understand the C7 computer which is a completely different animal than the C6's. Redline is also working on their version of the C7 with different ground effects, performance enhansments and of course the twin turbo's. Check them out online to see some artist renderings of this new super ride.

im not a big fan of people who...
out of attempts to look intelligent...
shrug off things like they are no big deal.
The attitude of something being a piece of cake, when its pretty obvious extreme caution needs to be taken...
protrays pure ignorance and carelessness.
Any shop saying they have tuning the new c7 down to a science...
i will encourage them to post a video immediately of a vette let alone a silverado with a turbo system on it.
And if that person does not, I encourage them to leave this page immediately because ive lost all respect for their attempts to look intelligent.
In other words....
Where is your video doug@ecs of your piece of cake tuned vehicles?

by no means am i saying its not possible, and it cant be done...
i just hate when people dont have the common sense to know when their bragging scares away business instead of attracts it.
Post a video of the piece of cake silverado with a blower or turbos on it, and dyno's.
Otherwise, lets be realistic and humble for a second, that this new ecu and tuning process is going to take some attention and is no walk in the park, and that NO ONE has succeeded yet.
because im pretty sure thats the fair statement no one has the humility to state.

But i have a feeling, you would have posted those already, as would anyone, who has succeeded.
Again, please post, and make me eat my words, and my car will be in your hands along with a large check.

The ignorance level has reached a point in this thread that I no longer need to reply. Do your own research, there are a bunch of threads and video's on line. This isn't the only forum out there.
Good day.
Good day.

We are working on complete packages for the C7. This isn't just going to be top-notch suspension, we will have aero/appearance upgrades, and several power adders. I'll start a thread in a few weeks with some updates on what we have been working on.

and if you guys can post up videos, i will be the first to apologize.

i guess im having a hard time understanding why hp tuners is still saying they are working on cracking the c7 cpu...
and meanwhile ecs hasnt talked to them about their ease of doing this exact task
and i dont see any ecs vids on this forum of tuned vettes or pickups...
but you guys have time to type long paragraphs instead of post links to vids...
about what a piece of cake it all is.
Sorry for being skeptical and unimpressed with people who write paragraphs instead of simply post a vid.

all im getting at is...
you would think it would be common sense for someone to post up some evidence to this if they had it figured out... when there are so many people saying its a scary task.
... if that shop wanted someone to just blindly write a check and ship their car to them.
I can brag i can open up a tune...
doesnt mean when im done messing with settings, my engine doesn't explode 5 min later.

im having a hard time locating a vid of a turbo or serious supercharged lt1, pickup, corvette, engine rack dyno... anything.
So since im so horrible at using the internet... if someone would be so kind to post up any vid of a lt1 engine... the 2014 model of course
on this thread...
Since... no other threads on bette forum or ls1 tech have them either.

The active differential (if equipped) and suspension, much like the electronic stability control, are not tunable by HP tuners or EFI live as they reside in the body control module.
I have no idea what you meant by "pedal control" though. You mean throttle? That's an ECU parameter.

I only have one question for ECS and other shops looking at tuning the C7:
What are you planning to do for fueling???
The reason I am asking is because I've had to do some custom fuel injector design work for my job, and modifying GDI injectors is a real challenge. I don't know of any shop that offers oversize GDI injectors, and the traditional solution of increasing pump pressure will only take you so far. Here is what I think will happen, based on other GDI engine builds and what I know about the injectors:
-Mild builds will be easily accommodated by increasing injector duration and/or commanded fuel pressure.
-Low boost applications will most likely outrun the fuel pump ability to maintain pressure and will require a redesigned high pressure fuel pump (no trivial undertaking seeing as this is a 3000psi pump that is driven by a cam lobe).
-Medium boost applications will run out of fuel pump and injector room.
I was going to guess that people will be adding an extra set of port injectors to meet fueling needs, but now you have to figure out a way to control them, since the factory ECU only has eight injector drivers. a Dual ECU solution is non trivial. Resized injectors are non existent, and even if you designed a high pressure fuel pump that could feed tons of fuel at high pressure, the injectors can only be held open for so long before you run into some real problems (start injecting too early and cylinder wall impingement will dilute your engine oil and cause cylinder wear. Continue injecting after ignition and the cylinder pressure will prevent much flow from going in).
I am very interested in this. I've contemplated talking to my boss into letting me work on aftermarket LT1 high pressure injectors but I want to see what the aftermarket has in mind first.

now that some intelligence is around, ill keep my sarcasm down.
Im interested in solving this. Im also debating throwing an ls7 in a c7 and calling it a day, lol
But in all seriousness... how impossible would that be? I have an extra.

because like 7 billion other people on planet earth right now...
i have yet to see a new LT1 engine accept any serious boost, and not explode.
And as I attempt to brainstorm, instead of take large shops assurances that they have it all figured out...
we have now come to find that there are... NO LT1's on planet earth with serious boost that run properly, because they will run lean... according to an individual who actually builds and works with direct injection fuel injectors for a living.

powerlabs, the injector in the link, i assume is the one GM is currently using? or is that your suggested upgrade?
What injectors are porsche using in their 6 cylinder cars that are keeping up with 1000hp?
Simple logic would tell me their injectors, if used in a vette, should yield over 1000hp, since we have 8 cylinders worth of fuel, vs their 6.
