MitsuStyle - View Single Post - Dealing with boost creep and running lean

**1ViciousGSX** · 11-01-2003

Are you running the stock MAF or is it hacked?

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

Put BPR7ES plugs in it, that may help with the knock also.

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

Regardless of the boost creep, it is still running lean under power. The O2 voltages need to be over .90 which should also help with the knock. .90-.94 is close to where you want to be, but this varies with each car and set-up. The ECU adds fuel based on airflow, boost creep or not it is running lean on you.
