Hi guys,
Im soon going to receive my 14 Evo X and was looking for some advice. Im not looking to do any major mods for the first couple of years. After I get it, Im going to get a cosworth air filter and then a tune. First thing I wanted to know is if there are any cons with reliability, daily driving, fuel efficiency, or performance after getting a tune. Also, does anyone recommend a tune shop that has a dynojet in Orlando? Do you guys know what price I should expect to pay for one in Florida? Any help is greatly appreciated.

At least would like to know of a good place to get a tune in Central Florida

 

Better daily driving, better fuel economy and better performance. There are no cons with regards to a tune bar possibly the warranty with mits and, of course, tunes are reversible

I know the performance and fuel efficiency is better seeing it tune the air to fuel ratio but I have always heard and even read some places that because it fine tunes settings for different speed ranges that it puts wear on certain areas more than stock. Which inherently means it needs more service. Although I'm unsure how true that part is.

 

It is really going to come down to the tuner/calibrator that tunes the vehicle. Typically a custom tune will work well and optimize the tune for your atmospheric conditions, fuel quality, etc. With that being said, there are good and not so good tuners out there that are more than willing to "tune" the car for you. I am not sure if you will be going with the Accessport for your engine management, but we do have a list of our Protuning shops here. These shops have to pass certain qualification to become a COBB Protuner so they should be more than capable of getting you taken care of. Some of the shops also tune via opensource if that is the route you choose to go. I would recommend giving them a call, discussing your goals, and building a game plan from there.

Nice to see that the shop I was thinking about using is on that list (titan motorsports). I dont hear it mentioned, but Ive always assumed there were at least some cons to tuning, otherwise why wouldnt mitsu give an "inferior" tune.

 

When Mitsubishi engineers design these cars they have a different set of parameters that need to be hit for customers needs. Things like fuel mileage, emissions, engine longevity, someone using 87 octane, etc. must be taken into account. This typically leads to tuning being much less aggressive than it could be.

When you increase boost pressure and ignition timing, cylinder pressure is going to rise. From an engineering standpoint that is going to cause more wear on the internal components of an engine. Most experienced tuners will know how far they can safely push a car, but you have a lot less leeway when it comes to things like fuel octane than you would with the factory tune.

Modifying a car will always be a trade-off, and enthusiasts typically value performance over things like NVH, fuel mileage, etc.
