Dealing with boost creep and running lean

[Alpine TSi]

1ViciousGSX:

Are you running the stock MAF or is it hacked?

Stock

When the timing jumped up to 41 deg were you still at WOT or had you let off the accelerator?

I had just let of WOT and actually had a knock of 11 that went up to 18 at the same time.

The O2 housing and cat-back could be contributing to the creep.

I had nasty creep before yesterday that got slightly better when I put the new O2 housing on.

Is your o2 sensor good/new/accurate?

I don't know, it was pretty white when I did the housing, but if needed I think I have a new one in my glove box to change it with.



Thanks for the responses, but why would I run lean on 510's? Any ideas?
