    • 637 wheel horsepower for a BMS JB3 Stage 1 piggyback tuned S63TU F10 M5 - Why even bother with the Switzer P700 tune?

      Great results here from an F10 M5 with bolt on modifications running a JB3 piggy back tune with an extra 2.5 psi boost increase. Modifications include catless downpipes, RPI scoops, K&N filters that delete the carbon element, and 93 octane pump gas with an unnamed octane booster. The car still has the stock intake system (just changed filters) and stock exhaust after the downpipes. On a Dynojet in STD correction the result is 637 horsepower to the wheels.

      It will be interesting to see how the flash and piggyback tunes come along for the F10 M5 and the result will likely be similar to how things stand in the N54 twin turbo scene which is each having their own strengths and weaknesses. The JB3 tune for the F10 M5 only costs around ~$300 (it is not listed on the BurgerTuning/BMS website yet) making it a great value.

      That begs the question, why does the Switzer piggyback tune that with similar bolt on modifications put down 633 wheel horsepower on a Dynojet cost $2000 more than the BMS tune? Why? Because M5 owners generally have disposable income and don't know any better, that's why.

      These two piggybacks are doing basically the exact same thing. BMS states their box is actually more advanced. They actually are even considering raising the price. It's crazy but what is even crazier is burning money for no reason. The dynographs below speak for themselves:

        This is awesome, awesome news. 650 whp should be very doable then with say, full straight pipes from the DPs back. I knew eventually the piggyback tunes would come in strong for this engine. Right now, we're looking at about 750 crank hp? I fall in love with these cars more and more every day. Great work.

        So this is basically a jb+?

        It's technically similar to having two JB+ systems as each engine is bank is run by its own DME. But same basic concept.

        The M5 and M6 are just monsters with this. Unreal power.

        Thanks for the info Terry .

        Been behind a few new F10 M5's here... great looking car (sound not so much) but with the above and E85 around 700 whp makes it compelling competition for my new M4 purchase

        E85 is not compatible with the tuning on these platforms, yet. Maybe some day once we have the ability to create a back end flash to go along with the piggyback.

        Terry, what is the limitation right now to making more power? Is this as far as you can tune to right now or is there a mechanical limitation you've run in to? I would love to get back into one of these when they can make 750whp+

        On the s63tu I've really not spent much time trying to tune beyond the Stage1 levels. So can't answer that yet...

        We need to get a USB cable (of our own) to adjust the setting

        Working with customers s63tu's is tempting me to go out and pick up our own. The ~470rw from the n63 just isn't cutting it anymore. I'll go see what's out there.

        Don't worry n63 guys we'll still keep our 2011 as well for development. Click here to enlarge Our collection is starting to get ridiculous. Fortunately Jon just bought a home with space to build the 8 car garage of his dreams. We'll be able to tuck some BMS cars in there.

        That would be impressive...

        You can always talk to me about picking up project cars as well. I'm not against picking up rides that benefit the forum.

        The setting change isn't that important. Technically if you don't make it the only drawback is the tune runs around 1/2psi more aggressively than its set at.

        @Legionofboom @Terry@BMS Wouldn't bigger turbos be hard to do due to placement and space constriction┐┐??
