Also the turbo scoop on the crankshaft was with the tuned version much larger and rounder and with the normal version quite stock.
One of te 2 was new so the guy could not tell the difference but I expect more RPM with the tuned version which may have to be lighter geared
In the attachement all engines from yesterday
