If that's all the boost you're seeing, you don't have it. You should see boost up around 18 to 19.

More like up to 21 to 22!

I've got a DDM tune but see 21-22 max and the power is similar to the GMPP. Get the tune. You'll be schocked at the difference. I saw 15-16 at full throttle prior to the tune.

Actually that would be standing still.

this car is quick,even the steering,going to take me a few days to get used to the handeling

Your old car was a very high performance car, but it was big and heavy man. This is a whole different kind of car.

There's a pressure sensor that gets changed out with the tune. The original uses three screws and the replacement two. This is perhaps the most sure of the easy ways to tell if the GM tune in installed.

[GS Stage 1]

GMPP tune:

TMAP and MAP sensors are changed out to 3-bar sensors. The new sensors have a blue sticker on them and are held in place by only 1 screw. (the stock 2.7 bar sensors are held in place by 2 screws)

There should be a sticker inside the gas cover hatch that says "Premium Required". (but not everyone bothers to install the sticker)

Boost command varies greatly with ambient air pressure, air temperature, turbo efficiency and altitude. But generally speaking: A stock car will pull about 14-16 PSI peak boost at sea level, or 17-19 at 5000 feet above sea level. A GMPP tuned car will pull about 20-23 PSI peak boost at sea level, or 23-26 at 5000 feet above sea level.

GMPP tune will enable NLS.

The steering is one of the things I don't like about it but your perception of it being quick is accurate compared to what you were used to before. I wish they'd had a delete option for the power steering on these cars.

i wouldnt try nls with the gmpp tune, you have to hit it perfectly between 6200-6500 and if you miss the car stumbles. if you want a reliable way to do nls plus have 2-step then get a wotbox.

The kappa is designed to deliver the boost necessary to achieve the designed torque. At sea level and in cooler weather, the boost will be less than at higher altitudes or in hot weather.

The 15-16 sounds about right for a stock tune at cool sea level, so I doubt you have a tune.

Man. Wrong year, wrong color, wrong tune. You really should take it back.
