Normally it should have seen around 375wHP (assuming I had a true dual exhaust).

That's a lot of work for 350 whp... I thought the HR made boosted power comparable to the VHR? (I have heard it actually can make more)

If you get stillen's factory tune, it is only 330-340 to the wheels.

Kaizens claims to be super conservative for customer street cars. They had a couple 370z stillens that did 437wHP with the upgraded 9lb pulley.

For example... 370z here made only 392 on stock Stillen set up:

still no new news. Kaizen's couldn't figure out what the idling issue is after the wet intake filter incident. They are having someone from nissan hook up Consult to it this wednesday.

--- really annoyed now. almost 1.5 months at their shop

Picked up the Z yesterday. Pulls like a mule. Has a little idle issue and it threw a cel for high idle. I plugged a logger in and saw the STFT at idle were high. I saw positive corrections(adding fuel under lean conditions), which makes me believe there is a vac leak.
