URD MAF Sensor Calibrator?

Looking at purchasing a TCAI from URD. Do I REALLY need to purchase the MAF Sensor Calibrator or is this just an add on? I don't want to cause any potential issues with my stock MAF.
I am also a little hesitant on manipulating any fuel tables or maps that are stock on my Tacoma.

 

Just an add on. Suppose to help with performance.

 

I really like the URD design of their TCAI versus a K&N not to mention URD is cheaper...

 

Don't get a k&n. Usually I would say that a cai is just a waste of money. But the urd one is about the only one that shows any improvement over stock. It's nothing to brag about but its something.

 

Maf cal is a bonus........ I like the afe stage 2 si better tho

 

Better fit/finish...... No cutting sheet metal, no chance of rain hitting maf element leading to stumbling, and for some of us, no blocking of heat exchanger

 

Are you referring to the URD TCAI? I read in the product description a small piece of sheet metal is to be cut to run the CAI behind the grill

 

yup..... U get a template. It's not hard, but in the end not worth it either IMHO. U won't see any cooler temps than stock past 35/40 mph.

 

no cooler temps however noticeable improvement in performance. No huge gains but gains nonetheless

 

AFE? XRU? dont quite know all of the lingo yet sorry

Required, no, desirable, yes. I installed both a few years ago. Ran just the cai for about six months before I installed the maf cali. With the cali, you should feel a little kick when you get to 3-4k and open loop operation. I like mine and they're staying, and I have a habit of removing anything that I don't think is doing anything.

But you do need to cut some sheet metal for the cai, but at least now the maf extension is included and no wire cutting and soldering is required. For me the soldering of the maf wiring was the biggest PITA.

Afe is another brand of air intake. The age stag 2 and the urd one is about the only one people around here will recommend, for good reason.

 

Difference between the Pro 5 R and Pro Dry S for the AFE application? Which should I get? Will either purchase the AFE or URD....URD is slightly cheaper

 

Disregard last post...the AFE is SIGNIFICANTLY more expensive than the URD...should I pay more for the AFE???

 

Pro dry filter is.....DRY (no oiling)...... 5r needs oil..... Urd used a dry filter.... Iirc its amsoil, haven't had one for a couple yrs

 

Why is one cheaper than the other?

 

One is pre 2012, the other 2012+

 

$424.95 product for 2012+ gotcha. I was hoping to save some $$$ but want to ensure I am buying the right part. Thank You

 

Website is saying it will not fit my 2015 only 2012-2013...I thought it would work for my 2015
