Installed LT's, SES Codes like herpes So I installed my LT's last week and they sound good and all except, Im throwing some odd codes. These are race headers so no AIR or EGR which Im not worried about those codes. I'm worried about the fact Im throwing a code for low frequency for the MAF (P0102) and low heat efficency or something like that for the front o2's. Whats the Deal here? the O2's are still good, I just put them in not long ago. When I accelerate from a dead stop or a roll (1st & 2nd gear) the car stumbles and pop's like crazy. Whats the deal here?

Vac leak from the air or egr systems...I'm speaking from experience! If not you may have a bad o2 extension. Did you block off all the wgr stuff? Even at the throttle body?

Headers cools the exhaust more than stockers do. The O2 sensors are probably running cold. The Bosch 13111's mentioned by MTB have higher wattage heaters in them and waaay longer cables eliminating extensions. Many here use them. Find them on Amazon or eekbay starting under 50 bucks each.

Most standard O2 sensors are about 12 watts. The 13111 is a higher wattage, about 16 watts. This is why when people swap to them, their problems go away.
If it wasn't a higher wattage, problems would remain.
Shevrolay, I know you've done your homework on O2 sensors and participated in many threads here about them, certainly more than I have and I consider your opinions and conclusions valid.
Perhaps the Bosch tech just wanted to blow you off.

This is the truth. I've had an O2 code that has bugged me for two years. Tried two different sets of stock O2 sensors, same deal. Two weeks ago I ditched the stockers and extensions for 13111's, code went away and hasn't come back. Not to mention they look much cleaner and were the perfect length.

I hate going on internet myths and like proof when I can get it. I put in a call to the folks at Bosch. A guy got back to me about an hour later. He said they don't have specific O2 sensor specifications available for them to see, but he did confirm that many are 10-12 watts while higher performance and/or newer cars are 16-18 watts.
I guess this is as good as we're gonna get as far as an exact answer to "what is the wattage difference" question.
What prompted my call is the that despite searching all the "Bosch O2/ higher wattage" threads here, on a few other forums and internet searches, nowhere is the exact wattages actually listed or documented.
