TRE max-lock rear diff first. ACD tune 2nd, engine tune third.

 

Open air intake setup.

 

A set of sticky tires

 

Same.

 

Bump

 

Bigger turbo. Which will obviously require a tune. Lol one mod... Once you get that bigger turbo you'd need all the supporting mods so I wouldn't just stick with one mod for your evo.

 

BOV for sure! adds around 30whp...

 

first thing i had done to my bone stock evo ix was window tints. I ordered a bunch of go fast bits which will hopefully be here soon. But I would have to say I'm happy with having every window tinted.

So yeah, tints

 

ohlins, by far the best single mod. altho the rear diff mod is good but its not present in everyday usage.

 

I know I'm beating the dead horse but, Driver, Driver, Driver!
No single part will get you anywhere near as fast as a day of professional traing.

And to show I don't have a stick shoved up somewhere, 1 mod= Fart can. Not a cat-back, just the can.

 

for single mod I would do a ecu reflash

 

Living on the edge..lol my Caddy has limo tint on all windows.

 

I would say suspension or exhaust! Either one will do me fine on a stock evo.

 

Only 1..... tune I guess.

 

Suspension or exhaust?
