Is there a need to remap ignition timing? Or should I use a pre-configured map and do a whole ecu flash? (and where could I get my hands on a preconfigured map)
-
Is an EGT sensor needed?

Are there any crucial tuning points there are to worry about that are not already listed?
I apologize if these are dumb questions, I am new around here <-- clearly.. and I have never built my own boosted car, so this will be my first(worked on others however... used to spend time in a tuner shop in California).

Tuning
Factory widebands are sufficient for tuning in this platform if you know what your are doing and know how to translate the data into usable info that you can rely on in making changes to the tune. it is really no rocket science but experience does come in handy.
Here is the manual for our turn key tuning solution

Monitoring
The more the better, overdoing this will not hurt you, But would i put an EGT on 500HP setup ...probably not .
Good luck
