I have a DINANTRONICS Performance Tuner Stage 3 For BMW F32 , F36 4 series. ( not for MPPK )
I had this installed in my car since March 2018 and i am going to sell this tuning software to put it back to stock. It has a great performing software can hit the speed up to 160mph+ <-- real test i haven't able to drive over $160mph yet but it can pull over 160mph..
Dinantronics tuner still under the warranty, i still have the receipt of the installation from the local BMW dealership . You can control the stages by your smartphone app as well.
Dinan tuner stage 3 required you have an upgrade intercooler, intake and exhaust ... With all these your car can be close or over 400hp and torque.. If you have a down pipe upgrade. It can easier be over 425hp..
