Hey, tnx for the remarks.
I did the calculations again and the outcome was a smaller positive EV

You mention you play tourneys. Have a question about that.

Take a SnG for example and we're in the first level. Everybody still has aproximately 100BBs. So lets presume that the above-mentioned action is slightly +EV.
You're the BB. Is this a good move?
No cause basically you put your "life" at risk on a risky draw with too little Folding equity, or yes because it's a (slightly) +EV-move.

Maybe bad example, but simplified: Is a +EV action in a SnG always a good move?
