MAF Calibrator really worth the money to get better mileage?

i recently put on 265/75r16 nitto terra graplers and put in a K&N cold air intake do u think a MAF calibrator will help correct fuel to air ratio on my 4 banger?

 

good question

 

I think im gonna wait until i put my lift, headers, an exhaust on before i call urd that way they can do it one time an done thanks for the information guys.

 

They might have the harness for the 09's; I haven't checked in a while.

I plan on picking one of these for my truck in the near future.

 

True, but for those less mechanically inclined or do not want to solder/splice it is indeed worth it. The price increases with the newer models.

Wasn't the price for theses so high because Gadget talked to toyota about producing these?
Or
Am I thinking about something else, perhaps the devil horn emblem?

 

I will be hopefully keeping this truck till it dies out(if ever).

My first vehicle, although scary to mod, its learning

 

No 09+ harnesses yet for the MAF Cali. As I recall, Toyota has has some legal hold whereby no can make them without Toyota Mamma's permission. I think that Unichip has gotten by this, but APR and URD have not. Not sure how the new UCONN thing is doing this either.

 

You will never recover the costs of adding the MAF Calibrator in MPG savings...
