Default Correcting AFR

Now that I have my wide band installed I can see I'm running rich 10.4-10.8 under boost (18psi) and 12.4-12.6 cruzing.

How can I correct this without going to piggy back? (I will be piggy backing in about 3 months)

It is weltmeister chips and a bursch bypass.

Drop the fuel pressure if you have an adjustable.... really you may be stuck otherwise till you get your controller. Thats why you are buying it afterall as you cant do it now! By the way, you will be getting a decent amount of bore wash and rooted spark plugs etc with those AF's.

What FPR do you have, stock or 3 bar? If a three bar go back to stock and retest

You can always turn up the boost to match the fuel

Ahh I tried the boost, it takes 19.5 psi to level out to a 12.2 AFR in 5th gear.

It is a stock 2.5 bar reg right now. I will try the adjustable, where can I gat one? who has them for the best prices, any one on the Phoenix area?

Maybe the stock FPR is going bad?

They run rich when they fail, but THAT rich???
