Is there a list of common tuned out items??? I have a 02 Z28 that I would love to start modding. My current plan and please correct me if I am wrong is... tune out

rear o2's
air injection
skip shift
increase speed limiter
increase rev limiter
altered tune for a lid and k&n filter

This would all be towards the future modding of the car. Any particular sponsors that anyone would reccomend for doing these modifications?

Thanks Chris

P0141 HO2S Heater Circuit Bank 1 Sensor 2
P0157 HO2S Circuit Low Voltage Bank 2 Sensor 2
P0158 HO2S Circuit High Voltage Bank 2 Sensor 2
P0160 HO2S Circuit Insufficiency Activity Bank 2 Sensor 2
P0161 HO2S Heater Circuit Bank 2 Sensor 2
P0420 Catalyst System Low Efficiency Bank 1
P0430 Catalyst System Low Efficiency Bank 2

These are the EGR codes:

P0400 - Exhaust Gas Recirculation Flow Malfunction
P0401 - Exhaust Gas Recirculation Flow Insufficient Detected
P0402 - Exhaust Gas Recirculation Flow Excessive Detected
P0403 - Exhaust Gas Recirculation Circuit Malfunction
P0404 - Exhaust Gas Recirculation Circuit Range
P0405 - Exhaust Gas Recirculation Sensor A Circuit Low

These are the AIR codes:

sorry kind of old thread, but hey I searched!

so to clarify, those codes above can be tuned out will no ill effects to how the car runs correct??

my tuner supposedly tuned out the AIR, EGR and rear 02 codes. guess not cuz the car is throwing some of the codes above.

if you have that stuff deleted then all you will be doing by deleting the codes above is making it so it won't throw a light. It will hurt nothing.
