Protune VS AccesPort VS OpenSource

So i have owned my WRX for a year. I am looking for some more power. Here is what my car has on it right now

Turbo XS Up pipe
Turbo XS Down Pipe
Turbo XS Full Turbo Back
Turbo XS TMIC
Walbro 255 Fuelpump
With Stock TD04 turbo

It is currently flashed to Accessport Stage 2, how much would i benefit with a protune or even an opensource tune? I mean would it be worth the $$ with sufficient gains?
Also i dont even have the access port anymore it got stolen or lost somewhere between moving from ohio to michigan. So what would i have to do to reflash it without the accessport?

Opps maybe this should go in the tuning section, sorry move at will.

I'm not sure about an unmarried ECU and reflashing with another accessport over it. I know when i got my car there was an unmarried AP on the ECU but I use opensource and reflashed right over it. Talk to a local tuner. Unless your waiting for a turbo upgrade, I'd say go ahead and get a protune, it's the healthiest mod you can do and your car will love you for it.

Protune it unless your planning on going with a turbo upgrade soon. It'd be better to have the Accessport and still get the protune so that they could load the protune map on your accessport. But, a protune is a lot better than keeping that rich map running on your engine. I think Jave crisped some valves or something running a stage 2 for about 2 years without a tune. Which is the reason he did a engine swap and turbo upgrade.

Opps the parts i have are the
TurboXS uppipe
Invidia V3 downpipe
Invidia 4" Titanium tip catback

Ok well im not planning on a new turbo any time soon cause they are awefully expensive but my birthday is coming up in august and i think that i will get a protune as a self present. Now i just gotta find a place in muskegon michigan to do. Anyone know any good spots? I did also notice the stage 2 map runs rich.

Add a set of injectors to that list too since you already did the fuel pump and TMIC. Modded stockers work well. It'll make for a nice setup for a tune as well as provide everything you'd need for a turbo swap down the road.

Just a tune done specifically for your car by a professional tuner. You will get the most out of all the mods you have with one.

Don't forget there's another option out there. You can have maps tailored to your mods, altitude, gasoline availability etc. by a number of outfits. I use PDX tuning maps, and there's also Dom tuning and TDC to name a few. That was my best option, since I live in the lovely place known as "the middle of nowhere". Is Muskegon near there ?

^ yeah I went that route but nothing beats having a pro sit in your car laptop connected either road or dyno and tune based on the cars reactions.

There is a place called all speed performance in muskegon. Looks like they only have a two wheel dyno though. Im going to give them a call see what their prices are.

Don't do it!! Your going to need a street tune if you take it there. Because you won't be able to dyno it on a 2 wheel dyno.

Okay so i talked to Brian at all speed and he told me that he could only do a street tune, not a dyno tune and because i dont have the access port they would have to install a piggyback ecu with a wideband o2 sensor and the cost would be 600 for the ecu and sensor + 500 for the installation which includes the street tune. Is it going to be worth the 1100$ for this over the stage 2 map or should i get the cable to hook it to my laptop and try to tune it myself or get a dom tune?

call dom or PDX if you're not within reasonable distance of a 4wd dyno
