The Official Superchips Forum

The check engine light has been on for a while now. It's supposed to be because i had the cats removed, but i decided to check the DTC's andI received the PO133 AND P0153 trouble codes. Is there an additional tune that i would need? When i initially bought the flashpaq it didn't work correctly on my car. the car wouldn't actually move until it hit the 3rd RPM. At that time all i had was a K&N intake and dual flowmasters. When i install the K&N tune i could feel more horspower, but it still seems the low end torque is not there. When i set the car back to stock it's worse of a lag and i get the codes again. Please help. thanks.

its because your 02 sensors were relocated with the exhaust.

hope this helps

so does that mean i've gotta replace them or would simply be fixed by a tune?

i think most people on that forum recommended a tune although i'm pretty sure they were using the sct x-2 tuners not superchips.

i dunno if superchips offers a custom tune like that but i'm guessing they probably do. ask.

thanks. yeah that's what i'm trying to do since i've already got this one and it's too late to return. That's plan for now at least.
