        Now we’re talking..

        Finally loaded the E30 tune today. I’ve been running your 93 tune for a while and although my Fuel mileage took a hit, it was a nice upgrade from the 91 tune. This one had me back up above 30.1 at 60 mph cruise down A1A. Performance is significantly better. First gear is almost too quick because it will rev out in less than a second to 30. I like it! I don’t plan on racing, but I wouldn’t be shy lining up next my old mans Z06.. and definitely quicker than an STI 😜

        If you’re considering a good tune look no further. Short of engine work, I couldn’t imagine much more power out of the 2.0. It’s a whole new experience!

        Now I know how fast an STI feels!

        I've always wondered how fast an STI feels. This tune satisfied my curiosity. I'm loving this tune! I should have gotten this a long time ago. It really transformed the car without the modification that one would expect to do from a stage 2 performance. I drove my WRX from LA to Vegas and back the day I flashed this tune and had a real blast! I have always dreaded getting on the freeway and yielding to all the fast cars approaching before merging into the a lane. Not anymore, I now have full confidence in this car so that when I punch it, it moves and I can feel the power pulling hard! Also, since premium gas is now around $5 per gallon in Los Angeles, adding 5 gallons of e85 is actually saving me around $15 per tank and the added hp/tq from the e30 tune is a win-win situation. I strongly recommend this tune to anyone and not to wait too long like I did.

        Just buy it.

        5th tank with the E30. Out here in PHX my pump only offers E54! So my ratio is 1:1. Real easy to mix to E30. Been st E35 and have had no issues. 3rd gear and up come alive. 2nd gear above 4k puts you back in your seat.

        I change my oil every 3-4k. Everything has been fine on the Cobb parameters. At times it runs a tad bit lean. But nothing to worry about since octane is usually at 97.

        Fergie and Jesus

        The Stage 1 93oct tune was Fergie and the e30 tune is Fergie and Jesus combined. This woke my car up to the point I am no longer looking at a stage 2+ package. The amount of performance you get for the price is just baffling. Instead of a gift for my anniversary I just took my wife for a spin and floored it down Lakeshore Drive. She said it was better than any gift I could have gotten.

        Actually we got in a huge fight because of it but the tune still outweighed the cons of the situation.

        11/10 should have installed this sooner.

        Stage 1 E/30 Blend OTS Tune

        First off I need to say not a dull moment with anything from MAPerformance for starters.
        Now as far as the tune is considered the tuner did a great job delivering the power while keeping in mind the Fa20’s Achilles’ tendon
        Which you start to notice in the tunes as you move out of the Stock maping this tune is the way the WRX should have come from the factory period the end. Awesome Job to the tuner who produced the tune. A good fuel blend calculator and an ethenol percentage test kit go a long way for peace of Mind. I might go stage 2 E/30 or build don’t know but I definitely got the bug lol
