p2261 and p2177 problem!
Has anyone ever dealt with p2261 and p2177?

One code says im running lean and the other says the system is running lean.

Could a boost leak cause this?

2261 is for the bypass valve

2177 is for pulling more than 23% of the fueling <=80% engine load.

What did you mod recently?
