Default Throwing O2 code!!!

I just had my car tuned... literally a a week ago. When they tuned it they told me my O2 were "lazy" and to replace them, so i did with bran new Bosch O2 sensors. 90miles later it's throwing the O2 sensor codes again.
Bad parts?
Any thoughts?

Also.. This car has no cats, LT's through to a 3in Y into SLP Lous Mouth.


Thanks,
Ross

Do you have long tube headers? If so this is a very common problem due to the 02's not getting hot enough to function properly. Many have changed 02's only to the the problem return (even the Bosch vette 02's). Easiest fix is to turn the code off (set to not reported).

Nope. It should no longer throw a code. When it does throw a code, it switches to open loop and runs rich.
