low miles evo x mod or not

Hello everyone,

I just purchased my 2015 evo x around last month with just about 1k miles on it. how many miles would you wait before modding the car? should I just fuc* it with the warranty and get a tune with the bolt on? also about the boost gauge aND everything, doesn't the cobb AP do the same thing? if so I rather just get the AP instead of the 3 gauges (boost, wide band, afr)

list of mods I'm planning to get

-UR resonator test pipe
- buschur crossflow cat back exhaust
- aem intake
- 3 point port
- pro tune by rs motors
- swift spec r spring
- h& r 15 mm spacer front and back with longer studs

i think i would just leave it as is since its tuned by rs motors already. and not sure what u mean by the warranty, after seeing that mod list, that warranty is long gone. if u get a cobb ap, u would have to retune it, and it can monitor the 3 things u mentioned.

sorry I should've been more specific about it. the list of mods are what I'm planning to get for the car. the car as of now is stock. that's why I was saying if I should just screw it with the warranty and go for it or wait. I mean if I get a tune by a reputable tuner I should be safe right? about the cobb Ap, couldn't I just use it to monitor the 3 things mention in my 1st post and not have to re tune it?

The access port doesn't monitor your AFR. The evo only has 2 narrow band o2 sensors from factory. There is a way of wiring the AEM gauge in so that the ap monitors it as well, but it's not something strait out of the gate.

I would wait. I got 2K miles in on a new FE and it started to leak oil. I would drive it at least 1k mile beyond your break-in fluid change.

As for the whole AP thing - I think (someone please correct me on this) it has to be "married" to your car. If you do not marry it, I do not think you can use it simply as a gauge. Once married, you will need to run their pre installed maps. You can always find someone to do a custom AP map for you but at that point... why spend 500 bucks on the AP AND get a 500 pro tune?

Just do the mods.

AP is good for monitoring boost, knock, coolant temps.

you'll need a windband for AFRs. As mentioned, you can wire a wideband into the stock wiring to the ECU, and then use the AP to monitor AFRs. But if you are buying a wideband anyway, you might as well just wire up a gauge to monitor with.

As far as worrying about the warranty, I wouldn't. Those mods aren't going to break the car (a bad tune could, but hopefully your tuner is decent). I've had significant warranty work performed on the car while being WAY WAY WAY more heavily modified then that.

For instance: full bolt-ons, custom tune, different suspension, different exhaust, different downpipe, replaced clutch, different ACD fluid, and I develop a leak from the t-case (which shares acd fluid). This was right at the 5 year mark and I had ~45k miles on the car. The leak is onto my new exhaust that ran really close to the t-case without any heatshield.

Mitsubishi replaced the seal in the t-case under warranty anyway. I didn't hide the fact that I had modified, raced, and abused the car.

So don't worry too much about what people say on here. I've had numerous positive experiences with numerous Mitsubishi dealerships when it comes to warranty work. Just be up front with them and they will respect that. An oil leak has absolutely nothing to do with any of the parts you've mentioned, so even if you should develop one they will work on it under warranty. Though the chances of you having that issue are slim, for the most part these cars are robust and reliable.

Anyway, just go ahead and do it if you want to. You'll be fine. I would just make sure you get a reputable tuner your trust, they are the only ones who could really cause you much issues if the tune sucks ***** and blows your engine. The car has been out for over 8 years now, the tuner should know exactly what it can handle and how to properly tune them by this point in time. (read: make sure your tuner isn't learning how to tune the evo x with your car, they should have had plenty plenty plenty of other x's they've tuned and learned on before yours by this point in time).

Yep agreed ^^^. I just took my new evo in for a warranty repair yesterday. Chatted with my Service Manager. He said that when an EVO comes in, they automatically assume its been modified even if the owners says it's stock. The dealer will take pictures and send it to some regional Mitsu rep for determination. If the failure is not associated with the MOD, the warranty will be upheld. It's really a case by case thing. (i.e. car modded with Cat back but engine blow - no way the exhaust can blow the engine therefore warranty will NOT be voided).

I bought a Cobb AP before I even bought my X. with 5 miles on the odo, I loaded the Stage I map, sitting on the plastic covered seats in the showroom, while the floor manager was opening the glass doors so I could pull out, then proceeded to drive her 250 miles back home. I went tbe and intake not much after that. 6 years and 90k miles later still running rock freak'n solid.

EDIT: I will add that I did change the oil first thing when I got home, and the other fluids shortly after (around 1k miles) and they all looked pretty ruff, especially the oil.

do you think the car should be driven past a certain amt of miles before modding? my evo has about 1300 miles on it. the guy I'm going to been tuning evo forever and alot of good review on him so I'm sure he's good. I was trying ro get the AP to eliminate buying 3 gauges cuz they're like $300 a piece.
this is a dumb question but is it possible to put on all those bolt on plus tune and still make it a reliable dd?

You're seriously going to do whatever someone from the internet says to do without doing any of your own research?

Ok, wait to mod your car until your warranty is up or whenever you realize that a wideband gauge and an AFR gauge are the same thing... Whatever happens first.

Do whatever you want. You already have your mind set on tuning. Just be prepared to pay for repairs if the dealer denies you, or maybe they won't care and fix it anyway. Or be happy with a tuned car with no problems for 100k+ miles... There's really no straight answer.

I know what you mean. I just wanted people's opinions. I've to admit, I really didnt know the difference between the wide band and afr but Yea now I know it's the same thing measuring air/gas. I meant to say oil pressure as the 3rd gauge. but it's all cool.

Here's a tread you should read up on. If you're not ready to deal with the potential outcome, I would 100% hold off.

Same here. Local dealer is great. They've never mentioned anything about the the picture thing. I'm running full bolt ons. They haven't said anything at all. Besides compliments.

Every place is different though... Some are a nightmare to deal with.

Like someone said before, maybe wait a couple thousand miles if you're worried to see if there are any serious issues/defects.
