I have had my evo x for a few weeks now. And while I dont plan on putting mods on it now, I was going to order them and put them on in the spring. I plan on doing some basic bolt-ons. Cat-back, intake, new intercooler pipes/intercooler. I have only had experiance modding NA cars. So just for those basic bolt-ons would I really need to have it tuned. I know for optimum performance and the most from them the answer is yes. But if I didnt right away it wouldnt hurt the car? And I know on some turbo'd cars a cold air intake can mess with the cars idle and increase turbo lag. So for an intake is my best bet a cold air or short ram? If it was NA i'd go cold air no problem. I just wanted some insight into this from experianced members since this is my first time modifying a turbo'd car.

 

You'll be okay on an `08 doing bolt-ons with a stock tune. The car comes with a very rich tune. A wideband o2 gauge would help you keep an eye on that.

 

You should be fine, but maybe atleast look into getting an Access Port.

 

What about for the intake? short ram or cold air?

 

You don't see many cold air intakes for turbocharged cars since the intercooler serves that function. Just get a larger fmic. It obviously can't hurt but they seem to cost more.

 

get a cobb AP and then get whatever intake is on that list. you will be fine. with an AP you already put out more power without any other mods.

 

congrats of the car and its good to see more local mass people on here
is there a reason that you dont want a tune?

really a tune is your best bet. AP is a great if you need to change maps often. If not a custom tune is the way to go. It will get you the most out of your mods. I would suggest putting a tune of some sort into any modding budget.

 

I do plan on it sometime during or twards the end of next summer. But as soon as the winter is over I just want to get some basic bolt-ons done. I want to put off a custom tune until I run more boost later next year. Why pay for something then have to pay for another one 4 months later.
