I don't run a emanace tune, but he does a very simillar thing I did on my own 240, except I did it for a SOHC.
Let me tell you, ROM tuning in my opinion is the best solution out there.
First off you get to keep your stock ECU, so no messing around with wiring. If you ever get into it you get to swap chips with what ever tune you want when ever you want.
And at the same time the car behaves like stock when out of boost.
Only thing you really have to watch out for with rom tunes is the person making maps. Cause like Brian said, some make them pretty conservative for the reason that not every car is the same.
One solution I used when I rom tuned my car was get a SAFC. Cause lets face it is kinda of a pain in the *** to get fuel perfect by making a map reburning the chip going for a drive and do over. Thats also the reason why they usually make these tunes conservative. There is also a rom emulation solution out there that lets you do this one the run, but that gets a little bit more crazy and requires soldering in daughter boards and such.
Back on topic, With the safc you can basically fine tune any part of your fuel map and not have to worry about it. But like mentioned before owning a wideband on a boosted car IMOH is a must. I hate driving cars that are boosted from factory with out one, so go figure.
As for timing, if its someone that knows what the hell their doing the know the area for the beast mean TQ on the specific engine, the timing is pretty much flawless.
If you are more interested in learning about more what emanace does, visit HybridKA They have gone as far as being to make rom tunes and use the stock ECU to run a map sensor.
