Finally dialed in my z4m tune

[rueyme]

Last month finally had a chance to bring my stroker s54 3.5 to the dyno and had Josh at severn tuning remote tune my motor. Had it done at two other tuners previously which both had some difficulties bringing it to peak, turned out the o2 sensors were swapped and only josh figured this out by knowing exactly the behavior of this motor and the ecu how the numbers should read. Picked up 30hp from the last tune. Highly recommend him if youre looking for best gains and still being within safe parameters for the motor.

Them some solid numbers!

30 hp extra? Scheisse! Josh is the man.

Thanks for the opportunity! This would be about 379 whp with STD correction- great numbers for 91 octane in a Las Vegas summer. That engine is strong!!

off topic, what are those wheels? they fit the car extremely well.
