Even if you do get help, the process would be easier and quicker if you set yourself up with an emulator like the APU1 and a wideband O2 sensor. It would save shipping multiple chips back and forth with the tuner, so the turnaround time would be much quicker. You could also learn some of the stuff that gets changed in case you want to do some tweaks or modifications in the future. The other advantage of using the APU1 is that the wideband O2 can connect to it and be stored as part of the log file, making it much easier to tune the open loop or WOT fuel. No-one can really get this part of the fueling correct without proper wideband data.

A Dynamic EFI conversion also gives the same benefits.

If you don't want to, then at least talk to the tuner about modifying the PCM so you can use a more readily available and easier to program flash chip.
