2008-2015 Evo X Mod Guide

These are the typical results from modifying your 2008-2015 Mitsubishi EVO X . The baseline was a completely stock 2015 EVO X Final Edition and we have the 2 most common stages of modifications from stock to compare. All of these results are uncorrected numbers which are 20-25% lower than you would expect to see on a Dynojet dyno or our “Shootout” numbers. For more information on comparing dyno numbers check out our dyno page.

Our starting point was completely stock. With no tuning, no modifications, and with 91 octane fuel.

This vehicle made 228.3 HP and 246.9 FtLb TQ on our Dyno at 20psi tapering down to 12psi by redline. The factory rates this car at 303 HP/305 FtLb TQ at the crank. A non Final Edition 2008-2015 EVO X makes 291 HP/300 FtLB TQ at the crank or about 216 HP/241 FtLb TQ at the wheels on our dyno, so most people will see gains of an additional 4%.

Below you find the information of our findings along with dyno graphs for comparison. If you have any questions about building your 2008-2015 EVO X, give us a call (763) 316-5882.

Stage 2

Stage 2 vs Stock

This stage includes an aftermarket intake, turbo back exhaust and 3port boost controller. This particular car had an ETS Intake, Map Intercooler/ Upper Piping, AMS Downpipe, and Cobb EBCS. This car made 273.3 HP and 306.5 FtLb TQ with boost hitting 26psi and tapering down to about 19 by redline. Tuned on 91oct.

You can expect to see about 19% or 45 HP peak gain in power and 24% or 60 FtLb peak torque gain. AT 3200-5000 we saw a 40 – 45 HP increase and from 5000rpm+ it increased to a 60hp gain by the 7700rpm redline.

Stage 3

Stage 3 vs Stock

This stage includes all of STG 2 plus the addition of Fuel Injector Clinic 1200cc, DW 340lph fuel pump and E85. This car made 324.1 HP and 328.1 FtLb TQ with boost hitting 26psi tapering down to about 19psi by redline. Tuned on E85.

You can expect to see about 42% or 96 HP peak gain in power and 33% or 81 FtLb peak torque gain over stock. We purposely keep the wheel torque below 315-325 FtLb to help preserve the stock rods.
