I applaud dealers for doing this kind of thing.
There are some caveats and concerns I have. Tuning "off the car" can be a complete minefield and I would only recommend to install Ferrari exhaustively tested factory maps from the Stradale on the 360. Not "custom ones" unless they are 100% proven safe on a dyno on your actual engine. The CS maps gains about 5hp across the board without any other changes and about 20hp more if you have a free flowing sports exhaust and they are very safe and extremely well tested under all load conditions, temps, fuel octanes, etc..
I would much prefer to validate any new maps on the individual car so you can test the setup is working on the actual engine (with its actual tolerances and current condition). I.e. so you can monitor the air fuel ratio's with a wideband Lambda sensor and check for any engine destroying detonation in real-time. There is no way I would put any other maps (untested) in my engine, what happens if they where done on higher octane than your using (it could go boom!). The Bosch programming will try to retard the ignition curve but if its not quick enough... You have too much to risk, its simply not worth the risk!
Really there is only so much you can do using 'generic' maps and in my opinion this isn't really real "tuning" as you never even see it running on the actual engine. Its just re-flashing a pre-existing map done for someone elses engine, not yours! This is something completely different and something which should be cheap vs real dyno based mapping.
I've got Stradale base ignition maps which I could donate (freely) to the forum, I've already explained how to (for less than a $20 cable) backup and restore the flash from your existing ECU. And others like 355Eric explained how to then backup your Immobilizer pairing data from the eeprom storage chip (so your remote works) - useful if you ever need to replace a broken ECU.
I even went as far as developing the s/w in C code to re-calculate the checksums for the Bosch ME7.x (so that you can transplant maps from one firmware to another) - again donated into the public domain for free. I really must update my github with the final working version. Even if you don't use my free version there are paid versions of the tools to do this for pretty low costs.
The only thing you then need to do is;
1. Remove ecu's from the car
2. Backup you existing rom/firmware and eeprom chips using a simple DIY wiring loom to ecu's (documented entire process and its not hard).
3. Clone over the Stradale maps into your own personal firmware/rom file. You must do this because if you don't you risk it not working (there are literally tens of variants of each firmware for different market segments and model years for all the various differences in sensors, emissions, even different code for Manual vs F1 etc.)
4. Run the checksum recalc tool so the code accepts the new maps
5. Flash the new file back into your ecu's then put them back into the car.
This whole process is about a couple of hours work (including the removal of the old ecu's from the engine bay). Nobody should be charging over $1,000 for this kind of "service" (investment in time, tools and software is relatively low on the 360). The strong exception to this is actually dyno tuning on the fly which can run into thousands but its a completely different thing than this....
Strive for perfection in everything we do. Take the best that exists and make it better.
When it does not exist, design it. Accept nothing nearly right or good enough.
