I own a 2010 Ralliart and I was wondering what are some good parts to start out to make more horsepower. I don't want to get an evo x right now because the jump in price is too much. Just want some suggestions on what parts to start out with.

 

I just bought a 2013 model myself.
What I've been told is the easiest/best upgrades are the bolt on ones, EVO X intercooler, replace the upper and lower intercooler pipes, bolt on EVO X turbo, ECU tune, upgrade SST's clutch plates, SST reteach, plus don't forget the transmission cooler.
That's a good place to start.

 

Start reading the stickies on the site but intake or drop in filter, exhaust, boost pill and an appropriate tune from here (https://www.evolutionm.net/forums/09...t-basemap.html) or a local tuner ask on the site the transmission makes them more complex to tune properly. Beyond that it gets exponentially more complicated if you want more power.

 

what most people do at first is get the boost pill/exhaust and flash one of the GST tunes in the link provided by RalliFast.
