Default please give me some imput on my setup..

Does AFR's on the UTEC reading around...

1. AFR ~14-15 on idle, normal?
2. Sometimes "lean" comes up between gears and engine braking, normal?
3. A lot of "rich" comes up right after I left off the gas, normal?

Mods:
Injen CAI
STI pinks
Invidia Downpipe
HKS Hiper Catback
UTEC stage 2 base map(<-- problem? using stage4 fuel map for STI injectors)

Thanks for any input...

1. Around 14.7 should be your normal idle at operating temp.
2. When you let off the gas your car is going to run lean so that it's not gaining anywhere. This way the vacuum it produces you will still be good. And between gear shifts, are you talking about WOT or normal driving?
3.CAI=sucks, I highly recommend a short ram. Because you can hurt your engine more than anything because those damn things have so many dead zones you have to tune for. Inorder to get any benifits out of them.
