Are there certain parts that after you install you need to get tuned right away? Im asking because as soon as I get my evo X im going to start modding it.

 

Well it depends what your getting. A tune is only gonna benefit you and should be done regardless, but you can still drive your car without having any problems. I had a tbe and intake on my car for about 1000 miles before i got a tune. You can tell a difference in power but after a tune your car isnt the same (LOTS more power.)

If your getting cams, injectors, bigger turbo, Intercooler kits, or other internals then yes a tune is required asap.

Basic bolt-ons you'll be fine but i would recommened you get a tune. Your gonna spend a good amount of money on an exhaust and intake and if u want to get the most out of those mods then get a tune.

 

My suggestion, would be to not buy parts focused around a tune. Any part you buy will perform better with a tune. hell your car STOCK will perform much better with a good tune. I debated this for awhile, and I opted to get together groups of parts. example, I am adjusting my entire airflow system. intake, intercooler + parts, full exhaust system(headers, downpipe, cat delete, Buschur cbe, and VTA BOV) doing these parts and then getting it tuned.

I have another batch of internal parts that I am going to buy after that, and then get them tuned. just my approach. However there isn't anyone here who can really vouch for aftermarket parts and suggest not getting a tune on them.

 

So even after an AMS intercooler and upper/lower pipes you have to get a tune... hmmmm. Thats why when installing mods I will be doing everything at once.

 

What i did before i got a tune was exhaust intake dv intercooler ulip licp then had my tuner install a fuel rail fpr injectors and ebcs then had them tune it.

Now im going back in 2 weeks for another tune w/ new cams and valvetrain as well as a tune for e85.

 

Tuning gives you an opportunity to take advantage of the combination of your existing and new parts. Stock Xs have power ready to be released with a good tune. English Racing took my hours old 2011 MR from 256 WHP to 307 WHP. That's excellent performance for the money. I wish all mods did that. You can also have a tune created for an application like track days with higher octane fuel, then switch back to normal when you head home.
