Hi Folks,
New member here, long time auto enthusiast. I have a 2013 X5 xdrive35i with 102k miles. I recently installed a Pure Stage 1 N55 turbo along with catless DP, charge pipe, turbo inlet pipe, intake, etc. Basically a full bolt on (except intercooler) for the N55 E70. I was hoping for about +75HP/TQ. I had the vehicle tuned by DynoComp in Scottsdale AZ on crappy Arizona 91 octane gas. I am not a fan of canned/internet tunes, etc... It costs more, but I feel it is safer. The numbers came back a little lower on HP than expected but she is a torque beast. Keep in mind drivetrain loss... so i figure my minivan is just shy of 400hp 500tq? Lmk your thoughts and questions.
