Get yourself a cheap laptop and a wideband and you can do all the timeconsuming tuning yourself - cruise, light load, throttle pump, onto boost transition, up to mid range RPM full boost (no futher than that though on public roads simply due to speed).
It seriously is not that difficult, and you can start tuning gently and get the hang of it with very little risk to the motor. You need one person to drive the car and one person to watch the AFR and adjust the ECU via the laptop.
(the final step in tuning equipment it a knock box and headset - about $900-$1000, but you can do most stuff without it and have the ignition timing in the power areas adjusted for max power during the short power tuning dyno session)
If you go about it this way the only thing that you will need on the dyno is 1 hour or so for the full noise runs up to redline.
If you are interested in learming how I'd be more than happy to talk to you about it via PM or even phone call. In fact, I could even video tape the next tuning session I'm soing for a mate with a turbo TE 250 cortina so you get the idea.
Anyway - just an idea mate.
