    • MHD Stage 2 A90/MK5 Supra B58 tune results on 93 octane pump gas with catless downpipe - 439 rwhp

      93 octane pump gas results are important as not only will the majority of MKV Supras see pump fuel the majority of tuned examples will not go beyond what the factory turbo offers. The MHD Stage 2 paired with a catless downpipe is the perfect daily driven recipe.


      There is plenty of punch picked up while keeping things reliable and not pushing the factory turbo too far.

      Just over 100 horsepower at wheels was picked up over stock:


      Notice the torque curve is not some crazy stump puller for peak figures but smooth and linear mirroring the factory curve just with far more area under that curve. The top end holds nicely toward redline allowing for a nice overall area increase in power on the top end from 4500 rpm on.

      Solid, reliable, and repeatable results.

        Great results for sure.... And as much as I wouldve liked to see the uncorrected figures, the fact they are disclosing the correction factor details is more than desirable from this sort of post. 7% correction is a bit high but at least you can see all the details backing up the correction, under those condition differences no one can ever argue the real improvement from the flash itself

        The B58 is the best mainstream engine released in the last decade. Really great results for basic mods!

        Impressive results but ambient temps and humidity differences are huge. I'd be interested in seeing the difference under the same conditions.
