Wondering if there is any damage done if I floor it at 1400 km’s? Or should I wait longer...?

You mean you haven’t floored it first opportunity off of the car lot?

Floor it. I found the speed limiter 5 miles from the dealer the day I bought it.

Common sense says to give it a little "break in" time before you beat it. On the other hand some of the fastest stock vehicles I've know was a fleet of Dodge Hemi powered police cars that were abused from mile one. Bottom line: I'll break my own car in before beating on it, but I'll be happy to abuse yours if you'll let me.

I’m trying hard to practice some common sense with taking the time to “break it in”. Wondering if 1400km’s is too early to test it out in Sport mode. By the responses here, it seems I may be ok.

You should be fine. If my math is any good that's something like 8 or 900 miles. Go ahead and stand on it.

I have always done 3-5 gentle heat cycles to seat rings and then its game on. Ill accelerate in a gear, hold the gear, and let the engine brake the car down pretty far then do it again. Trying to get high cylinder pressures and then a bunch of vacuum to really help seal the rings. Had a LONG TIME engine builder tell me about that years ago and its worked well. He does 3 gentle heat cycles and then runs it through 4-5 WOT/engine braking runs and calls it good. Ive done that on cars that "overall" were notorious oil burners and I have never had one burn a drop.

NOW as per the other components(trans and diff gears) that COULD be another story. The trans I dont worry about as much, but the axle gears, they really should get at least 500 miles of easy driving with a few heat cycles. GM in the C7 Corvette recommended nothing crazy until 1500 miles due to the rear end gears. MOST guys(including me) dumped the fluid at that point and almost universally it was NASTY...then it would stay pretty clean for however many more miles, but that first 1500 miles the gear lube was NASTY.

Thank you for the info! What is WOT?
