We’ve redesigned the N51/N52 tune from the ground up. Adjustments to Vanos, Valvetronic systems allow for more toque for the street. Adjustments to fueling and ignition timing help the car make big power up top, pulling the car faster to its new redline of 7200rpm (Manual Trans or Auto if you have a xhp tune).
Note: Late model N52 in the F10 & F25 are not supported with our iFlash cables and require you need to ship the dme in for tuning.
Stage 1 +12 – 17 Horsepower (For stock or lite modified engines)
Stage 2 +15 – 22 Horsepower (High Flow Cats / Exhaust modifications)
We also offer options for Lifter mod adjustments, Burble (pop and bangs) and intake swap (3 Stage Manifold)
Burble option is recommend with HighFlow Cats and to run with a set of aftermarket headers for best results Link https://www.magnaflow.com/collections/2007-bmw-328i-catalytic-converters or https://www.turnermotorsport.com/p-388468-afe-twisted-steel-headers-e9x-325i-328i-330i-2006-2013-e82-128i/
We DO NOT design tunes to defeat any of your emissions components. We are not in the business of getting your car ready to pass inspection.
