Does the Turbo effect the spark plugs ignition-flame-size when accelerating / when the turbo begins spooling ?

All I know is that if you don't fix the fuel/air ratio within the cylinder, you could damage your engine quite badly. You probably don't want your spark plug making giant fireballs now, would you.

No, the Turbo has no effect on the spark itself.
Actually, that's exactly what you want it to do

Ok so even if i changed the PSI - it won't effect the 4 rounds of the engine cycle ?

Increasing the boost may lead to pre-ignition, detonation or knock due to the higher effective compression and higher temperatures in the comustion chamber. The fuel air mixture may pre-ignite and that can lead to sever damage to your engine.
Running a higher octane fuel, reducing the compression ratio with a thicker head gasket or low compression pistons, changing the plugs or adjusting the ignition timing may be required to prevent any issues.

I see ... so the effect is focused on the engine 4 rounds cycle rather than the size of the ignition flame.
Higher octane fuel will help to evade the pre-ignition since the higher octane tends to burn better than lower octane fuel so that there can almost be no more fuel left in the cylinder X)
As i know in physics - a higher compression increase the temprature, so in order for not to pre-ignite the amount left of fuel inside the cylinder on ( the compression stroke ? ) a certain engine-round from the 4 cycles it's better to make a low compression adjustments / exchanging a certain parts in the engine as you've mentioned to evade that issue is what you're trying to say right ?
So i take it that the racing or sport engines does comes factory stock that way ?
For example like Mitsubishi GTO & Nissan GTR R35 ?
Since both got twin turbos.
Also i've remembered something - the reason for the exhaust flames or backfire is also caused by higher PSI ?
Or caused by a certain adjustments in the cylinder parts timing ?
