my truck was tuned using a different wideband than the one I have installed, which I was tuned to 11.5 AFR

After plugging my wideband back in and driving off I remember it not reading 11.5, but something lower (like 11.1).

Now (months later) when I go WOT, it reads 10.1

I have the aeroforce interceptor wideband kit. I've reset the sensor back to normal and it still reads this. At idle it reads correct (14.6+-)

any idea on how I could see if my sensor is bad?

Since the tune, I have had problems with my MAF acting up (having to clean it a lot or else it will misfire/idle horrible and some times die while coming to a stop) and also I think I am burning a little oil (not sure if these could effect the AFR)

 

If your wideband is calibrated properly, I would suggest getting your tuner to hook his wideband up to verify your not having any problems with the maf or something causing too much fuel to be injected. If his wideband reads properly then you know what the problem is.

 

where do you have your 02 bung placed?

 

sounds like the wideband is correct and your maf is screwing up...

 

SD tune

 

It is a KB racing kit, the bung is welded about a foot past the turbo in the down pipe

tuner is located 8 hours away, so that doesn't help. I guess the common sense thing would be to find someone local with a wide band to see if they would let me hook it up to get a reading


SD tune is definitely in my future! I can't stand my MAF
