I have a 2007 V6 with the following mods: Vortech Supercharger with Diablo Predator tune. Bullitt dual exhaust and 8.8 axle with 3.73 gears.
I get po172 and po 175 error codes which mean the engine is running too rich. I am not having a lot of success with Vortech. Any suggestions of what might be causing this and a possible fix?
Thanks,
Lou

 

have you tried putting your car back to the stock tune and then reinstall your tune for your supercharger?

 

No I haven't. Have you heard that that works?

Have you datalogged the car?

 

although I do not have a supercharger set up, generally whenever I get an error code I erase it first to see if it comes back, if it comes back then I re-install the tune. I have had both of them work before. If you are still having problems after that I am not sure what you will have to do.

 

Thanks! I will try the reinstall.
