Maf

Is there any difference between lbz and lly MAF sensor? I put a lbz cai and turbo mouthpiece on my lly, got a p0101 MAF code, maybe just come incidence but happened soon after the intake install

I believe it has to do with the bigger cai piping. Someone please correct me if I'm wrong. May need to retune for the change in size of pipe.

Ah okay, how does one re tune the MAF? Also I cleaned it with cleaner and the truck responds better now but still blowing that code.

Ah OK, found another thread about it. Apparently it does need a re calibration through efi live. So I'll have to get that done

I had the same problem and if you want a quick fix you can just get a piece of 4 inch PVC amount the math on it just get like a 4in length and then collar it to accept your open filter. I had the p0101 and a real loss of power. Put the collar on and everything came back to life and drop the check engine light

EFI tuning required for the increased volume of air.
