I am going through the exact same thing with my 16 WRX (MT) and am on the fence about the accessport because of warranty. I have researched alot though and have not really seen any negative reviews about the accessport, like engines blowing or any problems that might arise. Like you said though, The powerband is soo bad and it feels like it wants to go but its being held back....

 

The accessport wont blow up your car you wont blow your car up until 375/400hp and then you will bend a rod or spin a bearing. The biggest problem is these motors sometimes just blow up and its subarus fault but if you have an accessport they will deny warranty and put the blame on you.

im currently tuned and putting 335 to the wheels and the car drives like a monster wouldnt change it for the world. Stock tune is reallllllly bad in many ways

If you plan on keeping the car then buy an accessport and tune the damn thing.

Something to keep in mind when youre thinking about tuning the car. Every motor is different they all have a " sweet spot " for power. When you get protuned the tuner will find the best spot for cam angles/boost/timing/etc. Some cars may make more power with less boost than others thats just how it works. The preloaded maps you get from cobb are not tuned for YOUR specific car they are a very conservative tune that will work fine with ALL of the wrx's. You should get a protune and have a reliable/reputable tuner dial your motor in.

 

What made me shy away from any tuners... The lack of dyno shops near me for a custom tune.
I highly recommend having a custom tune while your car is on the dyno. This would eliminate any problems you are having. Emailing datalogs is part the way there but it's a mere guess and check game that way.

Also, talk to your tuner. Get to know exactly what was neede to tune properly. See if there is a discount in the future for add-ons and re-tunes. Generally there are since you already have a better base to work off of.

 

If you have a good tuner they can tune that out. This is a problem that has been present for quite some time through the generations. My tuner explained it as just being lean spots in the fueling curve, likely done for emissions purposes. My protune on my old 11 WRX eliminated the problem. I'm unsure if Cobb's off the shelf maps solve this or not as I haven't used one before. I would venture to say that it would at least improve it.

 

I'm curious to here this, looking to buy the stage 1+ kit and installing

 

Thanks, I will try and look for a dyno tuner in my area. We use the drag strip for tuning but only do it 3.5 secs a run. Not sure of the tuning in all areas or the power curve. Does anyone know of a good shop around Mobile or Pensacola?

 

Cobb AP Stage 1 - 93 took care of the stumbling issue when downshifting and passing by 2800-3200 RPM, have since been protuned

Looks like Runway Imports in Pensacola is your COBB Tuner Shop

 

Keep in mind, that a protune still requires the Cobb AP for the WRX's as no professional tuners are capable of tuning via opensource yet.

 

Thanks, I also got a suggestion of Driven performance shop in Pensacola.

 

I ended up getting the MAperformance map. It is a great tune... totally changed the dynamics of the car... I would highly recommend ordering the accessport from maperformance, they will send the tune for free.

 

Just beware that if you got a 2015 WRX with the recalled ECU or have updated your AP, that you can't run the MA Performance OTS... I loved it when I could run it (stock drop in, car bone stock)

Though the MA tune is a bit aggressive for daily driving, if you can't rip it it's not fun because it wants to be ripped, hard and fast like a cheap porno.

I wouldn't run an OTS as a permanent tune. I have seen the difference between pro-tunes and OTS and its a world of a difference.
