If you're gonna spend the money on tuning... why not add a few more power adders. The tunng charge will be the same either way, but in the end you might be happier with your tune and never want another...

Otherwise... you get tuned on the header and turboback, and decide later on to add a TMIC, Intake, turbo inlet, etc etc... and need to get retuned again.

Could not agree more!!! I got my 05 WRX Protuned about 5 months ago and am now putting on a VF39 and dare not drive my car for more than a few days without getting another Harman tune. This time i did even more homework tho.
i would also be careful of headers, they do give more power but u will lose more bottom end.

Big +1 for the top mount. It's the only thing I didn't do before my protune that I know regret with the 2.5L and the TD04. Without it you will max out at around 13psi on the TD04. With it Jarrad from PDX said 15psi is achievable. If you have any thought that you might want an intake get it done too. Intakes can/do change the maf readings and your tuner can fine tune this when he is doing your car. If you want a CAI i'd suggest tracking down one the older non 65 APS black CAI's since they flow more air. You however shouldn't put it on the car right before you're ready to tune since it's not the correct size for factory. I'm going to assume that your headers replaced/removed that cat in your uppipe. If not I'd suggest that too. Also talk to your tuner about spark plugs and if they recommend going one step colder. Jarrad said I could go one step colder and get some advantage but not full advantage b/c my setup wasn't going to push it that hard. Some tuners like the one step colder plugs others don't. Best to pick your tuner's brain on that. Pulley’s hoses and other misc things like that aren’t going to make such a radical difference that the ECU can’t learn for them. The three biggies though are the top mount, intake, uppipe, and plugs if recommended. You also might want to think long and hard about spending the money on a VF39 for the “STI” upgrade. I decided to skip that part since I knew I would ultimately jump to a bigger turbo than that and the TD04 tuned for the moment was worth the money.

Don't worry about the headers. On the 2.5L motor with that tiny td04 you have insta spool anyways and should have nice torque. Here is my dyno sheet. I think you will be happy with your protune once you get it done.

Exactly what is sitting in my office. Have the Walbro and pinks at home...
just need to buck up for the install and the tune...
on CA pump i will probably still be under 300whp tho. I figure if i can break into the 12s on my car i will be all kinds of happy.

You might want to get an upgraded boost control solenoid. I've read you can get faster spool that way. Perhaps someone more knowledgeable can explain.

Either you will need to get a specific y pipe OR be prepared to cuss a bit with silicon hoses to get things to fit correctly. I don't know the specifics off the top of my head not having done it yet but I do know neither of those (or any other top mount) is a direct drop in for us unless they specifically say they will fit the FXT/06 WRX. Also the recirc valve is different on our cars from the WRX and STI so you need to either get another recirc/bov or switch to the STI/WRX fitment along with the appropriate hoses.

*edit* A quick look around indicates that Gruppe-S might have an FXT fitment kit available for top mounts. Might be worth calling them to source the correct parts for fitment. *edit*
