If you have a wideband you could tune it yourself. the VAFC2 isnt hard to use at all you'd just need to see how rich, lean or stoich your running at a given rpm. If this is interesting to you, find a good WB02 with data logging capabilites and you can tune the car yourself, as aggressively or conservatively as you want.

The other issue would be do you street tune (find a long stretch of empty road, and pick a gear and take it to redline) or find a dyno shop that will let you use the rollers while you tune.
