CEL codes

I installed dynatech LT and High flow cats this past winter. I know that codes are normal until it gets tuned to eliminate the rear O2 sensors, but I wanted to make sure that I am not getting any unneccesary codes. Here are the 4 that I get most of the time.

P0153 - Slow response Bank 2 sensor 1
P0135- Heater Circuit Bank 1 Sensor 1
P0141- Heater Circuit Bank 1 Sensor 2

And P1153- Insufficient Switching Bank 2 Sensor 1

I might be missing 1 but that all i could remember.

Do i need to fix something or are these normal?

Thanks for the help

Nick

Some guys will have the tuner turn the particular code off so you see no indicator. If I continue to have these codes I may have that done other than throwing the codes the car runs like it always has. Good luck with yours.

My dynatech supermaxx system still had provisions for the rear sensors and I have no codes at all coming from them. The front ones on the other hand I get P0135, P0154, and P0155, which I am having a helluva time trying to fix.
