Re: retard timing to 13-14btdc

Since you have a turbo, a simple trick is to retard timing to 13-14btdc vs 16btdc normal spec.
If car is running lean, NOX will increase quickly. If car is running rich, HC and CO will increase gradually. Running 15-25% methanol/ethanol should lower all 3.
You're not that far out now, so the timing retard and methanol tricks should get you by.
To permanently fix high NOX, a new AMM, O2 sensor, and/or cat will be needed. If you're still on original cat, a new cat will also help turbo spool up and boost significantly.
