    2016 WRX acceleration

    I have a 2016 WRX with just less than 1000 miles. It pulls hard to about 4000RPM than it seams to drop off in acceleration. Going past 5000 seams like there is nothing happening. I mean it accelerates but not to the same intensity as from 1000 RPM to 4000RPM. Is this normal?

    It's normal. If you could see the power and torque curves of stock v protune there is a noticeable difference. Both the throttle and power curve are much more linear after the tune.

    I been thinking about a tune but the dealers mechanic said the warranty will be voided. However, if I can get a mild tune to make the power more liner with little risk to damage the motor I think I would do it. There is a tune shop close to the dealer that does WRX's.

    Why are you going past 5K RPM's at less than 1,000 mi. That's the real question.
    I have an STi with an intake and no tune, I never change my oil, and my wheel spacerz are mad tyte.

    Because. I have 954 miles that to me close enough and I plan to change my oil at 1000

    What makes you think it would pull hard past 5000rpm?

    The COBB Stage 1 tune fixes this issue. Among many others such as rev hang, and throttle positioning.

    Thinking about this how does this effect the life of the engine? I mean if I keep the revs under 7000 I should be OK? Not sure does this engine have a rev limiter?

    Not really looking for it to pull hard over 5000 but more even. It feel at 5000 there is a door got open very a lack of power, no reason to go beyond 5000 as there is nothing left?

    That not entirely true - depends on whether the Cobb tune is efficient at the location being used. Here the Cobb tune makes it better, and a pro-tune fixes it.

    There is a limiter, but consider it to be a safety feature rather than a driving aid. Even with a tune you will start to see the power curve lessen at around 5-6k, with more being available in the lower range of the next gear (play around and find the sweet spots). As for the life of the engine - a good stage 1 tune has the potential to reduce problems, while a bad one can cause catastrophic failure.

    I should add that when you tune your car you risk the chance of a warranty denial should something happen to your engine or other parts of the drive system.

    Probably true. I only have experience with the Stage 1 tune in CA. So I guess take it for what it's worth.

    I went with an E-Tune just before moving to CO, then E-tuned again for the non-CA gas, and higher altitude. Planning on two more Etunes here in a month or so for Stage 2+ and E85

    I am guessing you have a tune shop? A little far for me. Do you have a recommendation for a tune shop in Houston Texas?
