Nothing personal against Ash, but I have read some negative things about his tunes previously.

Unless you have a wideband O2 sensor, that air/fuel gauge is useless.

For a custom EPROM, if you already have a socketed ECU, there are many reliable and reputable options for a tune:

Harry at Ztuner:

Specialty Z: (they even offer an program switcher, which allows you to switch between up to 4 different programs for race fuel etc)

Glenn McCall: (Also sells Nistune)

And then of course there's JWT, which I've had in both my Zs and been very happy with:

Some include only the EPROM (chip) and you need to have a socketed ECU to replace this, and some include the entire ECU. Be sure to inquire as to which is which when ordering.
