Very good kit

Has everything you need. The only thing I had to modify was the L bracket for the throttle cables. The base comes very close to the lip on the throttle body. I could not get the coupler on. No biggy, just had to do some clearancing with a cut off wheel on the bracket and bobs your uncle. I do understand the harness adapters, plug and play make it easy for the common person. But I wish I could of had an option to get pre de-pinned connectors so I can have a seamless harness. I could always de-pin these and shorten the wires in the future. All in all great kit.

Good kit, tricky tuning

The machining on the adapter is great, and the LQ4 MAF is a huge improvement. but the kit does not come with the MAF Tables needed to run it. The idle set screw on my unit was also seized and the head was stripped. I understand my unit was used, but every other part of the TB was rebuilt and new screws used. I'm just surprised the Idle screw wasn't replaced.

Good kit! Don't know if it was my factory harness or the wiring provided with the kit but started getting intermittent connection loss so I just hard wired it all together and have not had any more problems with it. It also cleaned up the engine bay a little not having a big cluster of wires right there in front of my intake. I would recommend it.
