Better dyno numbers?
 

In general, You're probably pretty good as it sits now.

If you decide you need more, the easiest way for you to make more power would be to ditch the COBB and go with EcuFlash. I could be wrong, but I've never seen COBB do as good of a job as any other form of tuning.

From there you can always tune for e85 and swap injectors/fuel pump. That's relatively cheap and easy for the amount of power you will gain. On the bright side you won't sacrifice any of the car's response. E85 runs cool, so you can probably get away without a different FMIC, unless the X's OEM FMIC is really that bad (I'm not familiar with it's limits).

If you decide to do more on pump gas, you may need a FMIC (again, if the OEM part isn't up to task).

Like Kaj said, I would definitely look into getting a custom tune. With a tactrix 2.0 cable, EcuFlash and evoscan you can flash the map, log and even get e tuned from great tuners if there isn't one in your area. Can even learn how to do it yourself! Which reminds me, if you dont already have a wideband AFR gauge or a boost gauge, I would get them!

I'd recommend removing the HFC for a TP is you want max power.

But those numbers look good for those mods.

And if you are running a COBB ACCESSPORT on an EVO X, you should get rid of it and get over to ECUFlash aka Open Source. Main issue with COBB is that it doesn't have temp compensation on the boost control (ECUFlash does because of ROM Mods). With out temp compensation, your gonna over boost in the winter and under boost in the summer ie your boost will change with temps. With ECUFlash a good tuner can give you a boost curve, that is solid and the same, all year long.

As long as you aren't stuck with 91oct. If you are..well.. LOL
I ran 91oct for years, making 333whp. I had zero complaints. The car was still amazing.

Not sure where you are in North Jersey, but the Exxon at the Newark Airport Travel plaza has high quality E85. I go down there and fill up a few gas cans along with the car. Well worth it for the extra power.

Also, if you are close to New York state, there are several stations just over the border.

if you stay stock turbo the stock intercooler is perfectly fine for it. If anything i would go aftermarket upper intercooler pipe as the stock one tends to get boost leaks. its a mesh kind of fabric. with aftermarket you get a nice metal pipe. it helps spool up a bit quicker aswell. all thats left for power out of the stock turbo would be e85. if you cant get that and want more... time for a bigger turbo ;)

A mesh fabric UICP? Whaaa?

LOL... not exactly. The factory intercooler soft pipes are reinforced rubber. They are wrapped with a reinforcing mesh that reduces how much they expand under pressure. They aren't really leak prone but replacing them with hard pipes will nominally improve spool up be removing any expansion in the intake system.

I know, I have the same on my IX. I was just trolling because the post had so much misinformation 😂
thanks for clearing it up for anyone that happens upon this thread and reads it, though !
