I would say no. If you can't figure out how to find the thousands of threads and message forums dedicated to tuning a Subaru by yourself there is absolutely no way someone will be able to figure out how to actually tune.

↑↑↑ I don't think OP has a whole lot of experience on this forum or any experience tuning any EFI.

One has to start somewhere . . .

Once you can edit things like fuel and ignition maps you do need to have some idea where you want to make your changes, and by how much.

This is harsh, but true.

If you have to ask if something is possible, you really shouldn't be the one doing.

Me: "Can I just weld together an engine cradle?"

Forum consensus: "Of course! I have 45 years experience as a welder and it's easy"

Me (a little bit later): "So, nobody told me I had to remove the engine from the cradle first... You guys suck."

Hard to say if that ↑↑↑ is true in this case, where OP inly has 26 posts total, spread out over a whole year. He did ask about good tuners in his area in another thread earlier this month, and may not have got the kind of answer he was looking for there (or at least not yet; I haven't read that other thread for hopefully some further background information). He's apparently rebuilt the original motor (apparently it's from an '02, and no I haven't read the threads about that either).

Going only on what's in this thread, you and blurred may very well be right, that it is too much for him to tackle. Or with what we don't know about him, he might just have the aptitude for and willingness to learn as he [cautiously and conservatively] goes. It's not entirely impossible, particularly if he's willing to do some learning and research and can get a little guidance from time to time from those who have been there. Let's just say I've been there.

Could be that it was the way he phrased his question. Lots of people come up short in this respect, perhaps not realizing that how you 'say' something can be as important as what you say. Especially in this age where people don't communicate using more than about 140 characters at a time.

Just get an accessport. You can start with a number of base maps, learn the basics, and watch the logs. Then once you have your car driving like you want it download romraider and ECUflash and do your own tweaking after reading every inch of the romraider forums. It is very very easy to screw up your ecu/blow your motor tuning yourself.
