I'm not so concerned about an ITB spacer doing nothing, any application I've seen yields benefits but GGP seems like a newer / yet to be established company (not insulting them) so until independent tests are done with said parts - it's only guessing as far as I'm concerned. The pulley on the other hand has plenty of history NST has been proven and Been around forever + there are several dyno sheets showing results.I to have just ordered the pulley kit in red. Contemplating the red throttle body spacer but by the sounds of things ppl seem to say stay away or does nothing.
Is it a quality or customer support issue? I hate buying cheap crap - had issues with Megan racing before... Hopefully these are isolated issues and not the latter as most people who are satisfied won't post any reviews.NST seems to have a lot of unhappy customers online I hope we don't get the same treatment that I have read
GGP looks quality and his customer service is great from what I hear so that's a plus for me...and the fact he took the time to make products for us when others are "too busy" 👍It was there customer service nothing about faulty products. We will see how 19c and I fair out over the next few weeks. I watched a vid of the grocery getter throttle body on a new style 2.5 Camry and he seem to like it.
Did you disconnect the battery after for the car to re-learn?Ok, I got bored so I just went and installed the GGP spacer. Took 15 minutes and went to go get some groceries after I did it. LOL, just for giggles and to test. Honestly don't know if there is much difference. It seemed a bit faster off the line and in a dig from 30-50, but I would have to have more experience to say for sure. It was also a bit cooler tonight, so think of any gain as sort of like driving with an intake on a cold night if there is one.
Super easy install, and if it does create a little better response may be worth it for not that much, bolt on, and easy to install or go back. No problems or CEL or anything at all to worry about. (hardest part was making sure the O-ring stayed in place, which I used my silicone bike grease for). Will follow up later after more driving and different weather to say if I think it made an improvement. (BTW, already have TRD intake and Midpipe/catback, so it was already improved from stock substantially).
Anybody else feel free to chime in, but I thought it was a bit better on initial offline and mid-range "step on the pedal" type actions. Probably no HP gain whatsoever.
Disconnected MAF wire loom and took cluster off the silicone boot of TRD intake, loosened hose clamp from throttle body with flathead screwdriver and pulled off the airbox and silicon boot to move out of the way:

Access to the Throttle Body the spacer is going behind. There are three 8mm hex bolts holding it on that will need to be removed, one on top and one on each side below. The part is clocked isometrically, so you can't screw it up, it only goes on one way:

Total tools I needed to use. Stubby Tekton socket wrench (highly recommend buying one of these for working in engine bays and tight spaces) with a short extension, 8mm socket and allen wrench socket set (can just use an allen wrench for your install), flathead screwdriver, and silicone grease to hold the O-ring in place (use this or something similar that will not degrade rubber/O-rings always).

Final install with everything put together and tightened back up. Honestly, 15 minutes or less if you have any idea what you were doing. Took me longer to find my silicone grease and to write this post than do the install:

Reduction of rotating mass on a wheel will definitely help braking performance. . . .NOT a crank pulley. ..Rotation mass, not unsprung mass. Braking, on a CVT, maybe. Suspension, dunno.
Just IMHO. But the reduction of rotation mass should help in response, I suppose.
