    Hey guys, new around here. Been looking into a new car for a few months now and I stumbled across the greatest deal/car of our time, The Fiesta ST. I'M 100% in love with this car and can't wait to purchase my own.

    I read into some of the mods and people seem to recommend a tune or the MP215.

    With the MP215 what are you guys noticing? pros? cons?
    with the MP 215 you get the ECU modifier, would this eliminate the need for a dyno tune?

    if this is a poor first step to upgrading my fiST, do you recommend any other mods that won't void the warranty. I'm also highly interested in the RMM but after changing a few of those out in other cars it seems like any stock car needs a RMM upgrade.

    Hi again!
    and thanks!
    wayyyyyy too excited about this car.

    The RMM and the Quick Shift are probably the most noticeable mods in everyday driving. If you are concerned about the warranty, the MR215 is a real kick, but if that is NOT a concern, get the airbox and one or Randy's custom tunes on an Mtune. The rest depends on you and your relationship with your bank account.

    The charm of the MP 215 is that it's warranty-friendly, as long as a Ford dealer installs it. Same for the quick shift. Get both done at the same time, if you do it. The RMM isn't warranty-friendly, but if you're only doing 3 mods to your drive train, those are the ones to do.

    Yeah the MP215 seems like the best way to start.
    I don't want to get to mod heavy and damage the car for the long term. I feel like some of these upgrades that help the car run smoother will/might/pray will increase the car's longevity.
    I haven't looked into the quick shift too much but it sounds like a good idea if I'm getting a tuner.
    If I get the 215 first (which I'll prob do at the same time just to get it over with) will getting the quick shift later effect my tune negatively?

    I have a great relationship with my bank account. That's half the problem honestly I really don't want to spend too much for on the car after I purchase it. I'm sure the car will do great out of the box but coming from a sub 6sec mazdaspeed3, something tells me I'll be craving more umpuf before too long.

    I'm also sad that the RMM voids the warranty :(.

    The quick shifter has no effect on the tune since they're apples and oranges, so to speak. It's just easier to do the short shifter when you do the MP215 install because you have to remove the intake to access the shift selector shaft on the gearbox anyway.

    The RMM doesn't as much void your warranty as it's not covered under warranty.

    I have both the MP215 kit and the short shifter, and they make a good car much more fun on a daily basis :)

    I also have the MP215 and the short-shift kit installed and love what they do for the car. The fact that both are warranty-friendly really made them the only choice for me. Have fun!
