Cartuning GXP/LS4 Turbo Update
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You’d need to flash your PCM back to stock, and then we would reflash it with our software. Pricing on the kit is set at $5400 + 150 shipping. Everything sounds really good on the car, the only thing you won’t need is the KN aircharger, and you won’t be able to use the predator anymore. Not to worry, our reflash affects the TCM as well for shift points, pressures, etc!
Here’s a brief rundown of what is included in the kit :
8 x 42lb fuel injectors
Custom PCM tune
Turbonetics T-66 turbo
Turbonetics Evolution Wastegate
All piping mandrel bent, ceramic or Powder coated.
Cartuning W body intercooler
50mm Blow off valve
K and N air filter
High flow catalytic converter
DMH electric exhaust cutout with cabin remote switch
4T-65E shift kit
Lokar stainless flexible transmission dipstick
All PCV solutions
Direct bolt to stock exhaust
Full alky injection system
Fuel Pump rewire - racetronix
No cutting/welding required, can bring car back to stock with no problems
Turbo kit produces about 450whp(570 crank) from 250whp stock.
We still see stock or better gas mileage with the kit, on 91 octane minimum
required. The turbo really does increase efficiency, and DOD is left in tact.
We truly believe that this is the most complete turbo kit out on the market
today. Who else will give you a shift kit for your car with your turbo kit?
We feel this is an "all in one box" power solution that will give you amazing
performance, economy, and value.

I have e-mailed him to ask around how many hours of labor it will take so I know what to expect to pay for labor. Now I just need to find out who will install this. I'll probably call my muffler place (they installed the Magnaflow Performance Exhaust and my K&N Aircharger CAI).
EDIT: This is the response for how much time it will take.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We’ve done the install at a decent pace in 8 hrs. I’d guess 10 hrs + fluids. Honestly however, our installation manual is very complete... if you’re a shadetree mechanic you can perform the installation yourself in about a weekend.

Do you think their couple hours of dyno tuning would equal 1.5 years of CONSTANT tuning updates? There' s no way.
$1500 for install is WAY too much. Any reputable shop would do it in a day and if they charge you more then $100 an hour you need a new shop.
This one is in km/h since I'm in Canada and didn't think to change it before we ran...figured I would mention that, still impressive either way:

At the same boost as last time we made the same peak power, more peak torque.
However, we gained INSANE power overall compared to last time, I'll get the graph scanned and I will post it soon. The area under the curve is way more.

So, this turbo is almost providing a 90% increase in hp...based on a 245whp figure. WOW!
I honestly don't know if there is a big difference between two of the same model car. But even if I had a shop install it and took the normal tune, it's still about 6.5k. Man, that's a lot of money =P.
Aside from some minor things, a mail order tune for a turbo kit on a stock car will be VERY, VERY close to bang on because this turbo kit includes everything. If you have a cam or something different like that then I can see some tweaking needing to be done.
But if having one tune for every GXP is ok for GM....a mail order tune 1.5 years in the making shouldn't be too bad.
