that TB is impressive

I had to wait for mine as well.

Car tested good at Pocono. 3 laps to 170mph. Track and tires were cold (55). I do notice a difference in MPG! Using more fuel.

Jsilvester81

Great feed back.

since the car is using more gas, can you feel a difference in power?

I immediately drove my car from dealership to get cai
at my speed shop 3miles away so I didn't get to test if there was a difference w new tune

goshendad

it feels similar but like you, i put in the BMS filter after Pocono. I went to Carlisle and had Corsa install the Extreme exhaust. I will have the Corsa Helix X-Pipe installed by Friday and i am waiting on my Tony Mamo Ported TB!! haha. Another Pocono track day on Labor Day where i should really get to push it hard.

nice

you will love the throttle response with that TB

Does this effect 2016's as well or only 2017's?

goshendad

Only 2017's as GM changed the calibration for 2017 models.

I got the same codes and issues on my 2016 m7 a few weeks ago on track. Like exact same.

goshendad

Code P0106 was the issue in the 2017's. Do you have aftermarket bolt ons?

cwylie

BMS filter and corsa x-pipe

goshendad

Maybe its Pump cavitation in the Supercharger? I dont know. You need to verify the codes. Speed, temps?

How much does GM pay you part time engineers, to solve THEIR problems?

goshendad

They did right by me after I agreed to let them wire my car and the Stock car guys at Pocono gave me the track twice to test the car and record the event. I agree it is sad that they changed the calibration for the 2017 Z's and apparently didn't test the new calibration at track speeds above 165. With that said, however, I am a Corvette guy and I knew that a fix would be made so I can enjoy this amazing machine the way it was designed to perform. Mary Barra set everything in motion through Tadge and Jeff Strawser immediately upon receiving my email. I love this car and this platform. There is nothing comparable for the price.

The print out I was shown also listed the 2018's unfortunately.

goshendad

of course because they didn't figure it out til August 11. Any production before that has the bad calibration
