if u have the stock engine (108 hp) then yes it will affect alot. my old 90 standard hatch with 70hp was ok at acceleration. if i have three buddies in the car the car would just die of overworking on hard acceleration. it wouldnt even go. and yes just like ED9man said, Get rid of that shit u can put it back when you do a motor swap with 200 hp to the wheels or something.
