hi,
i have a 2001 wrx with ppp,full turboback decat system, fuel pump, iriduim plugs and panel filter. i have noticed my car is really fast from 0-95mph as soon as i go into 4th gear about 100mph my car seems really sluggish after ive hit 100mph. are they any mods that will help the accelaration between 100-130mph.

 

what mods would help this? please let me know soon so i can have them fitted before my car gets dyno`d on the 7th october
