So I purchased plenum spacers, a cold air intake, a z tube and MAYBE in the future a motordyne xyz pipe or a full catback evo3 exhaust.
Will these mods make me lose power and require a ecu tune or are these bolt ons fine?

 

You won't necessarily need a tune but its highly recommended. Deal with the cats beforehand though.

 

What would the difference be from with or without a tune? And where can I even get a tune? Will my local mechanic do it?

 

You have to have an Uprev certified tuner do it, they will reprogram how the ECU runs the car. You can either go to a shop and be tuned on their dyno, or buy the cable and reflash yourself at home with a tune file sent to you via email

Welp, theres no shops relatively close to me.. whats the degree of difficulty for the second option lol

 

Super easy. Just sent you a PM

 

g35fnatic did you end up getting a tune?

seymore4 would you mind also sending me a PM with details on getting the cable and doing a reflash yourself?

Thanks guys

 

Yessir working on that right now
