Running with no O2 Sensors?
I have a 2006 with four wheel drive. I have the AFR sensors in the manifolds and the O2 sensors in the b-pipes.
I just had Uprev install Long Tubes and Berk B-pipes. I picked it up yesterday but just got under it today to look at the stuff and noticed they had capped off the bungs on the Berk's. The O2 sensors are gone, the plug they attach to is sitting bare-ended (not good, need to at least cover that).
Since no one else has mentioned getting rid of the O2 sensors, I am wondering why Uprev did that? any thoughts? It's tuned and not throwing any codes despite the total absence of O2 sensors. They hadn't mentioned they were going to do that (or keep my sensors), so I am going to call tomorrow to ask but wondered if anyone else is running without O2 sensors and not getting codes.

Get your sensors back they are worth 125 each.

Maybe they turned the codes off with the tune.

Are the O2 sensors needed? I know you can bypass the codes with a tune... but are they really needed?

That set of O2 sensors is only to tell if the cat is functioning properly, they have no affect on how your truck will run. I have no cats just straight 2.5" b-pipes and had Uprev block the code. I went with straight 2.5" because my 2.25" with high flow cats was robbing power believe it or not.

Just curious, can you clear the codes with the bullydog tuner or no?

it wasnt the 2.25 pipes that were robbing the hp it was the cats...unless you have cams you will lose power and be slower with 2.5 b pipes...its been track tested a few times..

My 0-60 mph dropped by .4 with larger b-pipes? I know how my truck runs it truly does like 2.5" b-pipes I am running a 6.7 sec 0-60 on 35/12.5/20's at 4500' above sea level. Before the best I could do was 7.2-7.3 sec with HF cats and 2.25" b-pipes. I have done numerous data logs and promise you the difference was very noticeable. I know that I have read many posts saying that 2.25" was the way to go but my truck must be the exception. I also noticed that the climb from about 60-85 is much quicker.
