Has anyone had experience with the URD MAF Sensor Calibrator?

Is anyone out there using a URD MAF sensor calibrator for their 2.7 Taco? There aren't any choices for running a canned tune for a 2nd gen Taco 2.7L that I've been able to find, so I've been considering the URD MAF sensor calibrator. I'd like to know other's experience with them.

I have one, pretty much it will be you will be doing the tuning. the maps that URD sends maps to get started but needs fixing. If you want one I suggest to get wideband o2. they send the software to do custom tuning with it. Based off of R4 tuning software from split second. Goes off of throttle position voltage and RPM, below I have attached the suggested way Gadget (the creator of the product) how to tune it. For our trucks 10 is neutral, you go higher than 10 you add more fuel. Less than 10 take away fuel. YOU DO TUNING AT YOUR OWN RISK. if you go slow follow what Gadget says people get good results on other forums. Just search URD MAF tuning.
