    2019 X3 - new 3R93 tune results and questions - please read and give me advice.

    A few questions:
    1) Launch switch - how hard can you brake torque it safely? Just 2,000rpm? Floor it on the brake, realease 1 sec later and do boost launch? Or?
    2) I bought your blow valve and charge tubes as well - love it, but do not love it going off the entire time between 47-57mph. I adjusted it full tight and loose and it still goes off. Is this normal? What can I do about it?
    3) Lastly - with that tune, your full exhaust system, intake, charge tubes on an 1/8th (actually about 500’) blacktop spot where I test my car, it went from 78mph to 80mph. Picked up 2mph. That was with 5 gallons of 93 and 1 gallon of race fuel. It’s very consistent in terms of the results, 3 runs when stock yielded 78, 77, 78. Three runs after yielded 79, 79 and 80. I double checked everything, all connections are tight, no boost leaks. Waste gate adjustment and balance of your instructions followed. Is that the gians you would expect it to have?

    Thank you.

    yes, you can do a 5000 rpm power brake launch
    but it will probably cost you a belt
    you will need to raise your clutch engagement rpm to raise your launch rpm
    so the best power brake launch is just a few rpm over your engagement rpm
    mine is close to 3000 rpm

    stock clutch, don not use launch control or belt will be toast. You need a 2200 rpm or higher spring and you can hold it around 3k. I would only use it if you really don't care about your belts and how long they last
