URD Maf CAL Plug and play worth it?

Just like the title says. The URD itself is only 199. Is the $300 plug and play kit so I don't have to splice wires worth it?

 

Where do you see a plug and play kit? I'm sort of interested in doing this down the road. Any idea on how to tune something like this? Sorry for the threa jack, but free bump for you

 

I know there is a link to it if you'd search for it on TW. Unfortunately I am as green at tuning as you sound to be. I don't even know if the Unichip/ Urd Maf CAL is worth buying. Some say yes, some say no. I have the TRD CAI and JBA exhaust and headers and some say thats how you get full potential but others report minimal to no gains. If you get the URD itself its 199 but you have to strip wires and solder it in I guess. Or its like 299 for the Plug and play harness on their website.

 

I think he is talking about this plug and play harness, it looks like you have to but the MAF as well.
