A noticeable gain in power can be had with it. HP and TQ. Between 10-15 whp,depending on what other mods you have. And being the cheapest of the good tuning devices out there, it is a worthy investment for someone who wants a little extra power, as well as not a lot of coin spent.
There is a lot of tuning the URD MAF Calibrator in closed loop mode. You cannot alter the fuel mixture in closed loop mode with it, but you can do a lot of tuning there. We have other products that are used for altering fuel mixture in closed loop.

There are a lot of intake systems on the market that are not very well designed and cause a lot of significant induced MAF sensor error. For example on the 5vz the K&N Series 63 will cause the engine to run very lean and cause a significant positive fuel trim deviation. The Volant for the 1GR Tacoma makes the engine run very rich and causes a significant negative fuel trim deviation in closed loop from the ECU trying to compensate for it. The there is the new TRD for the 1GR Tacoma that make the engine run lean and a significant positive fuel trim deviation in closed loop.

We use the MAF Cal in closed loop to recalibrate the MAF sensor to the new tube and fix the induced sensor errors caused by poorly designed intake systems. Still tuning closed loop and fixing problems. So, yes there is a lot of closed loop tuning to be done with the MAF Cal.

You can also compensate for injectors that are different size from stock.

Just wanted to clear that up, the rest of the post is on target.

You sir need to read this thread.

http://www.tacomaworld.com/forum/per...os-w-mods.html

Then you will see that when you find your money tree, it will be well spent on increased power, as long as spent on good performance parts.

The power is there to be had, and the gains are proven. I don't care how anybody 'feels' about it. You cannot deny it.
