So I just bought my Grom about a month ago and already upgraded the exhaust with a TYGA. I heard that I also should order a new intake filter. I saw online that people have the "power commander" for fuel regulation and now I am really confused. Do I need the power commander? What upgrades should I do to increase performance but not have to spend too much money. I don't want to screw up my new bike so at what point do I need to think about getting this power commander or can I make some minor mods and get away without hurting anything.
