Hey guys, so I couple of days ago I had a TVS supercharger installed on my car. Since the install the car hasn't been restarting properly, idling properly, or even driving properly. Tonight the car through the check engine light and gave me these codes. Anybody have a clue what may be going on?

Was the tune properly installed for the supercharger? Maybe something happened during the upload. Since the problems started with the supercharger installation that is where I would look for the problem source.

thanks for the reply. yah maybe tonight I will reset the tune back to stock and reupload the tune and see what happens . just incase

I just realized that you posted in the S197 4.0V6 section (which would not have a TVS option). Your profile says 2017 GT so I am moving this to the correct section.

It’s either a tune issue as already mention or a harness got pinched. Where did the tune come from or who did the install!

The tune came from VMP and the shop who did the install doesnt exactly seem to have done this type of install too many times

JimC

Seems like you found the answer to your problem there. Something was done wrong on the install, didn't connect something back properly, pinched wires, or didn't install the tune even if they don't do this type of work.

Very well could be possible, what would you guys suggest ?

JimC

Have you confirmed that the supercharger tune is installed and that they didn't leave you on the stock tune?

what brings questions to my mind is this . afyer the install and after the uploaded the tune , they went for the first start up and the car was running horribly . The shop told me they did a throttle body relearn and that apparently fixed the car and made it run fine after that. So it makes me wonder if this relearn is not adding an extra variable there that shouldn't be there ?
