458 50 Amp relay upgrade for transmission pump?

I have a 2013 458 (9000 miles). Shifts amazing and perfect in race mode. In any other mode (sport or wet), the shift overlap is excessive IMO. Is there anything that can be done to sharpen/shorten the shift times in Sport mode?

 

I guess to clarify, the T25 relay for the gearbox is denoted in the manual as being a 30 amp (in my 2013), will upgrading it to a 50 amp sharpen the shift functions. This was similar to what is/was being done to the 599 and 430 transmissions (I know they are different...just giving a point of reference)?

 

Update: I had a ride in another 458 and his transmission in Sport was a little softer and had a little longer overlap between shifts than mine, so must be sport is more of a touring setting than a sport setting. I'll flush the transmission anyway (you should do it every 5 years I am told) and call it good. All is well.
