Default turboxs unichip - can anyone tune?

I bought my car used (2002 wrx) and it came with the tuboxs unichip. Can anyone tune this still or should i look to swap if for an AP or UTEC?

you COULD find someone to tune it, but it will be very difficult since just about everyone has moved on from the Unichip days...Too many drawbacks with the system.

I would suggest that you look into an ecu reflash for your car that is custom dyno tuned by either a cobb protuner or an ecutek tuner. That way, you get the best power and reliability out of your setup.

If you have previous tuning experience, then look at a utec. If you don't have any experience, I suggest you stick to the reflash from a cobb protuner or ecutek tuner.
the OTS maps are tempting and convenient, but since they were not made with YOUR particular car in mind, they can be off slightly sometimes..

Unichips are old technology at this point. You are better off with one of the newer reflash products such as AP or EcuTek.

Rallitek in Oregon tuned mine for me and they have a boat load of maps for it. A LOT of peopledawg the thing, but I have to tell ya.... it works. I have a freind with a Cobb 2.5 and my car was even with his with the vf39 and Unichip on 17.5psi. I obviously have no clue as far as how "safe" it is.... but I doubt Rallitek would send out maps for 12.5 afr's or anything. Another plus to the Unichip... I've gone through three setups that Rallitek has been able to send me maps for while Cobb is extremely limited unless you go get a protune. I don't live anywhere near a awd dyno... so I stick with the Unichip until I move up to the Hydra.

people dog the thing because of some of the issues that came up with using it...

If you live in an area where it gets really cold during winter, the car just won't start until you disconnect the unichip. Also there are occasions where the ECU and the unichp get into conflict as to who is running the show, and this shows up even on dyno runs. Also there are cases where the stock ecu adapts to the unichip programming, which defeats the point...

Don't get me wrong, unichip can work, but it is crude and unpredictable at times. On other ecu systems, they seem to work pretty well, but don't really seem to get along as well with the ECU's that Subaru includes with these cars.

I used to have one, and am speaking from experience.

This is true... some days my car felt really strong... some days .... not.

im still ahuge fan of my unichip stg2 thing flies my buddy has similar mods with a shiv tuned ecutek and any gear jump on it and i pull away considerable. Maybe the agressive tune is the reason. I love mine had it since 10k miles with stg1 now have stg2 since 22k miles last 3 years.
