The MK7 GTI…. The Most Tuner Friendly VW to Date

January 8, 2015

The MK7 2015 GTI has been around a little while and performance parts are starting to trickle in. As more of the parts come around we are seeing more data in regards to how tuner friendly the MK7 GTI 2.0T Engine is.


Let start with the basics. Generally when you are looking from more performance out of your turbo charged VW or Audi the best place to start is software. The reason why software is the best choice the get performance gains from your VW or Audi is because you get the most bang for your buck.


Info about Tuning Software on your MK7 GTI Here

MK7 GTI Tune

Here are the most common performance modifications on VW and Audi’s

  • Performance Tuning Software (Chip) – Gains on most VW and Audi’s 50-60hp
  • Free Flowing Intake System – Gains on most VW and Audi’s 8-12 hp
  • High Flow Down Pipe (usually with High flow Cat) – Gains on most VW and Audi’s 15-20hp
  • Cat Back Exhaust – Gains on most VW and Audi’s 15-20hp
  • Performance High Flow Intercooler

On the VW MK7 GTI however the performance gains from Performance (Chip or Flash) Software are much more significant. The numbers for the Unitronic Stage 1+ Software we put on our GTI are 76hp and 85lbft. This is a significant increase over previous VW models making the MK7 GTI the most cost effective GTI to tune yet. As you can see below from our actual at the wheel dyno numbers we saw an increase of 75hp and 43lbft. Normally when you look at HP and TQ claims from tuners your have to calculate for roughly 12% loss of power though the drivetrain (the transmission and other parts rob some of the power).

Here is the Dyno Sheet from our VW MK7 GTI with a Unitronic Stage 1 Plus Software Tune

    Do you have any recommendations as to which tune I should go with? I’ve been looking at APR, Unitronic, Eurodyne, and GIAC. They all have their benefits but I want the most usable power without any chances of blowing the turbo. I don’t intend on going full bolt-on. Definitely a CAI and possible an exhaust but the latter will be in a year or so.

    • Paul Barrett

      They are all solid choices. We are a Unitronic dealer so that is the tune we have. You should probably make that choice for yourself as we are not aware of any that are more likely to blow turbos in their current versions.

    Do you have the mk7 gti p3 boost guage that’s already installed in the vent housing with the track software in it,like Modded Euros? Also,does ur center exit exhaust have a resonator in it? I could not tell from the pics.Thanks,Marvin from Tx

    • Paul Barrett

      We do not have the track software on our gauge. The center exit does not have a resonator but does have a muffler. We shot our test drive video to talk about the lack of drone with this.

    Hey Paul, do you think that the stage 2 software is very important? because I’ve heard that literally all the gains for stage 2 come from the hardware itself and no the software

    • Paul Barrett

      Software is to compensate for a high flow cat in the downpipe as well as ensure the proper parameters of the ECM to make the most power with what you have. Keep in mind the software is relatively inexpensive.

    Hey Paul,

    I was wondering if you had some insight based on a tune related issue… I have a 2016 PP GTI DSG and I recently had my tune removed because of excessive flutter under boost inbetween 2.5-4K rpms, people keep saying its normal but I don’t believe that. As soon as I took the tune off no more flutter at full throttle and boost between those rpms. Any idea of what it is etcetc.?

      • David P.

        APR stage 1 93oct, also tried 91 file, both did it.

        • Paul Barrett

          We are a Unitronic deal but have not had this issue. You should reach our to APR to see if they can help or offer you anything.
