I think you likely have multiple problems now.

You have only owned car a short period and it was modded correct ?

I suspect it may have had tune at some point, the prevoius guy may have left tune in and the dealer has now flashed over it with stock rom.

You may also have the cam problems that were evident with early cars causing rough idle some were fixed with a reflash some required parts to be replaced like cam actuators ecu , oil control vavles or re shim cam sensor.

its ulikely the stock tune is going to run well with a injen intake especially the early model which wasknown to cause bogging and hesitation without a maf rescale and you also likely have catless header which will probably cause cel P0420 on the now stock tune.

As theother guys said you need at least a obd device to read codes and log fuel trims etc before you have any chance of sorting out what your problems are. You need to read cel codes from car to see if your getting codes for cat efficiency due your catless header or cam error codes due cam issues or rich lean codes due your intake or traction\vsc codes maybe due to stuffed wheel speed sensor or other issue.

or just take it to a seputable subaru shop forcthem to sort it

Ihave beentold by previous owner and the shop thatdid all the work that it was never tuned and ran fine. That they are all boltons that didnt need a tune.


Injen is sending me a new tube to fix idle.

I was stalling and sputtering BEFORE the dealer ecu flash. Cleaned maf sensor and put k&n oiled fillter on dry injen intake and then shit hit the fan. Cel and tcs lights came on and stalled
More frequently

My question really js jf the dealer was able to get into my ecu to add new software, why couldnt they get into it to see what the codes were reading. Wtf would i buy an obd scanner when tbe dealer is 5 minutes from my house. They dont use a 20$ scanner. Those 20$ scanners are garbage
