Megasquirt MS3 W/MS3X build
I don't think it would be a good idea to run an S4 NA tune on an S5 turbo. It'd probably get you started, but the spark table doesn't go into boost, and nor does the fuel table.
Honestly I wouldn't even give my tune to someone else with an S4 NA... Compared to the other S4 NA engines I've tuned, mine actually required quite a different tune (I'm assuming due the particular way I keep it for testing purposes along with the fact that my injectors probably need cleaned).

I am, but I have an S4 NA, and it's out of commission waiting for my shoulder to get better so I can fix the alternator and radiator.

Here is the most recent tune I have:

make sure you change the values on the injectors, including the secondaries... I'm running 2200cc secondaries... if you don't change that value, you'll blow your engine quick.
and yes, it's a decently old version of MS3.
