[safe]

Even though I'm confident in my skills to wire, setting up and getting an EFI running. I have limits, Its not easy or safe figuring out on the street if you can run 26 or 28 degrees of timing @WOT.
That you do on a dyno, so its just not worth the effort to do anymore tuning than you know that it works and revs up and can drive onto a trailer or to the tuner if its close. I like the trailer idea... with a winch....
There is plenty of stuff on the internet you shouldn't trust, fuel and ignition maps from other engines is one of them.
A simple thing as two injectors with the same flow rate but different brand/type doesn't necessarily flow the same amount of fuel. Or the exact same injectors might not flow the same on different engines because the voltage output from the generator isn't the same.
Having someone tune the engine on a dyno is the best money ever spent with EFI.

My 924 in the signature is getting back on a dyno in the spring after a clutch change so I can up the boost. Not something I would try on my own because its quite close to knock as it is.
