Are you running 91 CA crap gas and experiencing smooth stock like linear acceleration with your piggyback?
My 340 did not perform well (2 piggybacks) until I had it flashed and then it was just like oem on steroids / I'll be surprised if somehow the g20 changes that but I remain open minded because I have no first hand knowledge other than the f30 cars
If the traction issue you mention is wheel spin and granny intervention that's one thing (I get that but) but if what you are experiencing is the car wildly pausing between shifts and seem lost that's a piggyback for you on 91

Can't you just mix a few gallons of E85 with the 91 and have it run great? I think I'm just going to get a 55 gallon drum of E85 and put a few gallons in every time I fill the tank. Either that or octane boosters.
The E85 is $375 for a 55 gallon drum. 2 gallons should be enough with each fill. So once a week would come out to ~$700 a year. Worth it in my opinion.
