But after first pulling it out and while engine was still cold I decided to stab the throttle while out of gear. Engine cutout at 3400rpm like a rev limiter. So then I applied light throttle and as the rpm's increased, at 3400 the engine acted again like a soft rev limiter and with light throttle still the engine "hunted" between 3400 and 3100. It would go up and down in a sinusoidal kind of way.
I let the car idle for a bit until water temp was 85C and tried again - this time no issues and no rev limiter symptoms.
Do any aftermarket tuners enable a soft limiter until the car is warmed up?

Full power is not engaged until car is warmed up and in closed loop.
