TAP Chip. issue
Is anyone runnin a T.A.P. Total Audi Performance Chip on there 1.8T? Curious, because I bought my 99 with the chip in there and I am not sure which octane the chip runs with. I have always had a problem with my fuel/air ratio and wonder if my ECU is to blame. Could it be that the chip is for 91 octane and when i put 87 i run lean?

technically u probably aren't going to hurt your car by putting 87 in your tank, but you should be putting in atleast 91 octane burns longer, and with the 87 your having early detonation.
depending on the area ur from the chip will be a 91 or 93 octane.

read this, most likely u have a bad coil pack, maf, or 02 sensor if your having misfires.
do u have flashing cel?

Low octane is a likely culprit if you're mapped for a 91 octane. And if you're mapped for 93 and you're putting 91 in there won't be any misfires or stuttering, but it won't be power efficient. If you're in the west coast then your fuel is junk anyway.
