its from prosport. they are local too! go to their website, copy the address, paste it in google map directions and find it. they are about 10 min from where i live. The gauge, you can also get the 52mm if you would like. i had to go 60mm b/c my wideband is a 60 face. All of their gauges are pretty nice. the boost gauges range from like 40-80 depending on which one you decide to get.
My wideband on the other hand, was kinda pricey. it was well into the 300's but definitely worth it. Innovate is a sweet brand and SS recommend that i get it b/c it is tunable. IF you want to find this kit, it is the LC-1 controller with the xd-16 gauge. IF this seems to be too much, there is also the aem wideband. very nice as well. easier to set up and very similar.
Hey man, keep us up-to-date with the turtle. haha
