Are the stock airflow sensors being used, if so how are they performing?

Do you need to purchase upgraded hose clamps?

These are Great Questions! Here are some answers:

GXP 2007 and 2008? (yes Both Years)

Where did the tune come from? (Our own in house tuner)

Is this a computer swap or reflash via hand held tuner? (Either ECM Swap / Mail but no not a Hand Held Unit)

Where are the dynographs? (We are working them now, they will be available early next week)

Any customer feedback available? (Coming early next week)

Are the stock airflow sensors being used, if so how are they performing? (Yes, They are capable of reading up to 255kPa and we are operating with in that range)

Do you need to purchase upgraded hose clamps? (No but you will need to tighten the factory ones)

Timeslips, G Meter 0-60 or 1/4 mile times? (Have not gotten out to the track yet, also there are a lot of variables when it comes to track times)

I hope these answer your questions.

One more question, did you guys get your hands on some ECUs available for purchase along with the tune? It sure would be nice to keep the stock tune available for dealer visits.

Thanks Martin, a TON of us will be interested in this. Keep the info comin'!

Yes,

We are able to offer a tuned ECM for $700 (ECM $400 + Tune $300 = $700). This is a nice option for those who wish to swap between stock and performance tunes.

Any chance you could offer it in HPTuner format that can be downloaded from your website? It would be easier for y'all, you could get the same price, and the customer could get the tune sooner.

That is a GREAT price if you can deliver on the advertised performance increase etc..
With this announcement the Solstice\SKY community will start to see some good products at a much better price. (Competition)
What about BTF upgrade turbo wheel for the stock turbo and your tune, that combination would be really GREAT specially from a performace vs $$$.
Thank you
