forgot to remind you all what an UTEC is:
www.turboxs.co.uk
whether NA or FI 350Z, your mods will get the greatest benefits with a piggyback or EMS that makes the most of them, without the stock ECU messing around with A/F ratios. (my Z for example, instead of potentially running lean with the mods I have atm, it's running too rich thanks to our ECU )
NA modified like mine can expect in the region of 18-20bhp increase and a better power and torque curve after installation and tune of the UTEC.
This is a user tunable unit and can be used as a step towards your FI plans too, since with just a MAP sensor it's very capable of handling FI 350Z. It's the unit of choice used by many tuners in the US (see www.forgedinternals.com)
