S-AFC Tuning
you're going to need to add extra information to the post.. I.E. S4 / S5 . the S4 has been covered in searches like hi/lo being damn near the same high 90's.. haven't really seen a definate for S5's
You really need to get your car on a dyno and tune it on a dyno with a WIDEBAND oxygen sensor in your exhaust. This should be before your cat. Do not let them tell you anything different.
