Scram 411 vs. 410 classic - comparison

He mentions his Classic is "Tuned", I don't see how unless it has been on a Dyno?
Or running an AFR Meter because otherwise you don't have a real position to claim that except by the seat of pants/butt dyno.
 
well for us normal people without higher connections "seat of the pants" will do. It did for me, although I always welcome input from the scientific crowd with a home dyno in the garage.
 
I think therefore I am?
Well I could probably Tune a Piano with my ear, whether it sounded any good to others would not matter because I "tuned it"?
Same logic.
 
well, actually a piano IS tuned by the ear (at least before electronic gimmicks came up). I did mine in the 70s.
 
Yes and you made "adjustments " based on what you heard.
What adjustments have been made to the 411 build here?
Ok, none! Nothing to adjust unless he is using Powertronics ECU or fx pro, so no adjustments equals no Tuning?
 
This discussion isnt really helping. I guesss "tuning" is not clearly defined or at least there are variations how its used in colloquial language.
In my opinion a 410 is tuned by having a bigger displacement. your definition obviously differs.
 
My definition, the blue line is what I was able to do in respect to Tuning, and then for A$700 an expert Tuner generated the Red line.
I use my AFR Meter and the expert had a Dyno machine.
I know a bit about tuning ;)
