Help with Vortech plz
Since my Z06 Vortech is on its way already, and should arrive pretty soon, I thought of asking a few questions that should help.
I am going with catless headers and 3inch midpipe anticipating for similar outputs from the supercharger will LESS boost, and since the Vortech kit comes with the tune in a custom diablosport Predator, what should I compensate for the tune after adding the headers, to get it back to the way Vortech designed it to be?
I don't know how to say it any better >.<
Also member Pio suggested me to use a different type of oil (Mobil 1 5w50), anyone care to explain the significance?

As for the tune, be as conservative as possible!!

Do That........
if you don't have one already, install a wide band O2 to monitor your AFR's.
You will probably not need any more tweaking.
IMO, your tune will actually be closer with the headers because most mail order tunes are on the Rich/conservative side for saftey.
You should be almost spot on with your headers.
Good luck and enjoy your rare ride out there....

those people sure know how to fiddle around with dyno graphs, and people are unfortunately ignorant enough to beleive.The ONLY reason I choose the Vortech over the Procharger is because the thing comes ready with the tune, and I guess after adding the headers, I should just compensate for the A/F

The thing is, with all the debates on whether or not the LS7 could handle boost at high compression, I thought of settling with a conservative tune, taking into consideration of our weather as well!
The kit is 6.5 pounds of boost, but with the catless headers/midpipe I am looking for the same power with safer 1.5 lbs less of boost. I will adjust the A/F after the header install to get it to where the kit was designed to run.

i can under stand your point of view ( been there did that....), but still there are some good people with knowldge, they are harder to find and you have to dig to find out about them... take tariq performance, this guy knows LS and LT engines and knows every bolt on them ( trust me am not kididng every bolt), yet ppl say he charges alot of money and i this kind of talk, its the same about the tuners also, mario dont know any thing about gm cars, i am not saying he is not good, he did very good with the JPN cars.
BTW tariq uses the same method for tunning as the one you are heading for, he does the engine work then mail sent tune will do the job ( he deals with a friend of him in the US) , A/F to see if every thing is running as it should, if not he dowloads the data and sends it back to his friend, BTW where will you install the kit?

Supercharger manufacturers tend to keep their tunes on the conservative side. You can usually get away with running long tubes with the tune that comes with it but it's best to check your A/F to make sure everything is good. It's going to feel like a whole different car after everything goes on!

You may want to completely install the kit first and see what you get. I only get 5 psi out of my Vortech 6.5 psi kit, and it is working properly. There are piping losses, etc. Also make sure your boost gauge is accurate.
Plx devices makes a wideband unit and a meter for well under $350. You can install the wideband 02 sensor when the headers go in. Don't use a "wideband" meter that takes the data from the regular 02 sensors.

Oh man, both my boost AND A/F guages costed $200.00 together, there is something funny in there. Im guessing thats not a wideband? >.<
well ill tell you my plan is touching 600 RWHP (dynojet) with the lower boost possible, without having to install another fuel system etc...
I will update you guyz as soon as I receive the parts ^_^

I have the PLX myself. It works flawlessly.

$200 does sound pretty cheap. Make sure it's a true wideband utilising its own O2 sensor.
For the money you paid it sounds like the AFR meter uses your stock O2sensor which does not have the resolution that a wideband does.
OEM O2's are only accurate near stoic or 14.7. It will be hard to tell the extent of your lean/rich condition with it. They are accurate if you are dead on with your tune, which is never the case when you are tuning for addons.
I bet your boost gauge requires a physical vacuum line hooked up to it.
The electric ones are about $200 and use a map sensor for boost signal reference. Either way yours should be OK.
Just watch the way you route the nylon line it so you don't chaf, burn or kink it when you run it to your engine compartment for a vacuum source.
