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.

Great Mod

Great mod to increase the amount of air your supercharger takes in.
