Tune first off...your stock car is at about 230 WHP. Tune can get it to about 260ish maybe more. Few bolt ons like TBE, Intake, and Upper Intercooler Piping can really push out more powa too. With these mods though you'll probably wanna get a 3Port new BOV and some gauges to monitor your setup. Check out Hollywood's thread...good info.

I wouldn't get a tune first unless it is going to be a while before you finish your mods, no need in throwing money away. Boost control is going to come down to your chosen tuning shops preference basically, they may prefer stock solenoids, 3-port, or an MBC.

A wideband should be your first mod, there are some really nice options out nowadays that allow you to monitor wirelessly via your phone, computer, etc. For the money and time you spend trying to mount gauges, you could just spend that money on a more flexible unit.

That was what I was referring to. The lack of immediate options for a gauge mounting solution...

Let's face it there is AMI, Rexpeed, Perrin, Summit Racing, and Home Depot...did I miss any?

$189 from AEM, I wish I had gone this route or the Innovate.

Heres the list I have come up with

Ets V2 extreme (I like it loud)
AMS widemouth downpipe
Ams HFC
AMS intake
AMS FMIC
AMS UICP
AEM Uego
AEM Boost COntroller
and a tune

I want to do these mods I want to get everything on at once so I dont have to tune twice Let me know if I need anything else and what power I should get from this set up.

AEM Boost COntroller
You mean this?

If you get a proper tune you really only need a boost gauge to monitor it...and get an ECBS to help control your boost levels better. I thought about getting the TRUBOOST but honestly with a good tune it's not needed for a DD and minor track time.

Yes, but the terminology is awkward when suggesting things to people.

To me, the term "3 port" means a lot more to someone who doesn't know the difference between, say, an AEM TruBoost and the Grimmspeed EBCS.

Boil it down: Buy a boost control solenoid that the ECU controls.

Done.

Many options , look around some more and see what others are using and see what may work best for your budget and taste. Also be sure you get a good tuner in your area , a good tuner will make or break you !

Mustang or DynoDynamics (or 350 on a DJ :p)

300whp:
catback
HFC
dropin filter
3port
tune

350whp
as above + E85

I have not seen nor do I believe that the X will hit a true 350+ that can be backed up at the track, without race fuel or E85. The stock turbo is just to small. If you do every bolt on possible with cams and a aggressive tune maybe.

If you've already passed emissions and dont live in cali, you should be fine.
