i called, called, called, and called some more. i didn't get any response until i left a heated message on their business voicemail. still to this day, the only response after the emailed reciept was the message attached to the ups tracking info. seems like communication is not their thing.
on a side note though, i am pretty happy with the work they did on my rebuilt td04 with the pnp. the only thing that i wish they would have done better was to clean up the sealing surfaces to the up and down pipes. in the description they talk about resurfacing, but it looked more like the flanges were just wire wheeled or sandblasted. other than that, the pnp work looked really well done and the turbo feels great on the car.
