Better dyno numbers?
so I recently got a tune for my 14’ GSR and I’m definitely happy with the way the car feels. My mod list is
Cobb SF intake with inlet
Cobb 3 port
AMS widemouth DP
ETS HFC
Ultimate Racing dual exit
Excedy stage 1 382tq
Dyno 315 HP 335 TQ
my question is are there better combinations of parts I should’ve used to get higher numbers? I’ve read multiple times that intakes don’t matter much with stock turbo and I was told my exhaust set up is actually pretty good. Would a front mount make that much difference? What should I consider doing next? Different turbo and built motor are a few years away, just looking for some experienced opinions and ideas. Thanks everyone

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.

I do currently have an aem boost gauge and wideband in the car to monitor everything, I’ll start looking into evoscan and talk to my tuner to see what else we could do. I’ve been searching for E85 everywhere by me and it seems like I’m s**t out of luck lol thank you for the advice

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

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.

thanks for clearing it up for anyone that happens upon this thread and reads it, though !
