Running rich
 

I got supercharger installed about couple of months back. Randomly I started getting cel. Every time I read it. It’s showing p0172 ( system too rich bank1). So I started notice on how I drive my car and it appears only when I’m going over 4000 rpm when I’m shifting gears. Normally I drive like grandma on street. Rarely I get on it never redline it. What could cause on this? Is it a tune that needs to be looked at?

Maybe just sell the car and get a stock one. The only difference you'll notice is no CEL light! :)

HAHA I do take it to track. Just don't like to get a ticket for being stupid on road that's all.

Glad you saw my humor. Hopefully someone can chime in and help out!

I think your first call should be to your tuner...

This ^^^

I'll call the tuner to make an appointment to get this checked out.

Interesting. After 4 years of use, I suddenly started getting the same thing. Would a failing CAT do that?

I have art pipe so I don't know

ever sort this issue out?
