I currently have AP Stage2 on an 05 WRX with catless TBE,UP,KN Drop in.
My question is with a tune will I really be able to see a significant increase in HP on the TD04 or should I wait to get some other mods first. If so what do you guys think my next step should be? My goal is to get to the feel and power levels of stock evo. My car seems far from it right now.
I am in STL and I have been told to go to Ron for a tune at Axis Power Racing. Has anyone on here used him?
Thanks
