Much better tune than the OTS Cobb tune. More reliability and more performance. Slightly less efficient but that's a trade-off. Not as good as a protune but a good medium.

I ran the Cobb Stage 1 tune for about a week and it was an improvement from the stock tune. When I got this tune it felt even better. It does feel like it pulls harder. Definitely worth it by purchasing the access port from MAP

Think I got a bad tank of gas (shell) usually get Chevron, don't by Shell in California. Anyways was getting knock and Dam was dipping a lot. So I uninstalled all my bolt-ons and ran the stage 1 Cobb OTS. Still dam was dipping a lot and getting a lot of cruise knock at 19-25% throttle. Got some new Gas and dam dipped more but improved to .938 still a concern. Heard good things about this tune so decided what the hell. Got the tune and warmed up the car before install and after install let it idle for couple of minutes. Everything looked good. Did a WOT and solid 1 DAM and 0 knock. Happy with the results. Power is pretty much same as Cobb but MAP seems to do better on top end and RPMs seem to increase faster which is good. Overall happy. If I can will update in further to see if and issues arise. Why not 5 stars, well because I believe that there is always room for improvement. What that is I don't know,LOL

The map stage 1 tune is definitely worth it , now the car pulls all the way to redline.
Feels so much smoother and refined, should of came like this from the factory.
Checked afr’s , knock, dam all parameters are spot on great job on the tune.
Definitely recommend.

Highly recommend to transform the Subaru Wrx to a more linear throttle response and smother acceleration while at the same time eliminate the stock rev hang. The Cobb stage one tune does all that and add a slightly extra power. When you buy the accessport from MAP you also get there stage 1 protune which is just as reliable as cobb but more aggressive fine tuning for better performance. I love the way the car pulls all the way to the top of the rev band now. The driving experience feels smoother, faster, and sounds baddass too with the little bit of crackle and pop you get when you get on it especially in the low gears from the tune:) Finally these guys at MAP are top notch and answer any questions you have which is awesome. I even got to speak with Adam the protuner which was very helpful. Cant recommend these guys enough. Thanks again MAP!!!
