So long story short just spent a couple hours on the rollers to figure out that I am maxing my maf sensor out. Gets to about 11800 12000 hz and just hangs out causing my truck to lean out after 5000 rpms. I know I should be tunning speed density but is there a maf upgrade or what? I just spent all that time tuning and dont really have more time for sd tune.

Truck is a 2011 5.3l procharged 9psi with supporting mods. Thanks

 

Could my sensor just be bad and failing?

 

no your sensor is fine. I dont believe there is a maf upgraded OS for that year. You will have to go speed density or scale all of your tables.

 

I just realized I can tune the maf for half of my truck like 0 to half throttle and do sd for the rest. Going to get a 2bar and try it out .
