Ok, im going to try to make this question sound as easy as possible to understand.
For my 05 wrx with a turbo back exhaust, catless, what will give me the most gains after it's all said and done.
A dyno tune with stock intake, or a dyno tune with cold air injen intake.
There as simple as possible, will I get a greater hp gain if the tuner can get it right with the cold air injen intake??
Straight answers please, thanks again.
