Good point from bad press!

I good start would be to get the service/engine manual/specs for the VQ 3.7 VHR. Tuning is the art & science of any mod. The 370Z has many computers (5 I believe)that talk to one another... so it is not that easy to tune the engine's ECU without effecting other on board computers controlling safety, HVAC, and other operations. I am not sure if the various tuners advertise on this web site and/or other have completely crack the various codes controlling all aspects of the 370Z yet.

You have a good point, however when it comes to tuning, for me that is where my job ends and the professional's job begins. Not many of us, including myself, have access to a dyno nor the codes to crack the 370's ECU.

Luckily for most of us the the ECU flash that is provided with the turn-key FI kits will be adequate for most of our needs. Anything beyond that would reqire us to have our cars tuned at a reputable shop.

My past experince with tuner shops is being talked into crap I dont need which only makes the project budget skyrocket. I prefer to keep things simple and basic at first and go from there.
