BMW M5 tune. Nashville.
The S63 in the F10 (560-575 hp variants) and F90 (600+ hp variants) M5 is one of the most aggressively tune-responsive twin-turbo V8s ever produced. Stage 1 alone picks up 100+ wheel hp on most platforms. F90 Competition tuned past 850 wheel hp on flex fuel is documented territory.
Every Carma tune includes.

What we do for the m5.
Stage 1 unlocks boost, fueling, and spark across the S63's broad boost envelope. The platform is conservatively tuned from the factory — there's real headroom on 93 octane and dramatic headroom on E85. We've tuned F90 M5 Comps hitting 900+ wheel hp on bolt-on mods + flex fuel.

Common questions.
Will BMW detect the M5 tune?
Yes — F90 M5 platforms log overboost events. We offer free stock-revert before any planned dealer visit. Tell us your service-interval plans up front.
Stage 1 vs Stage 2 hp difference?
Stage 1 on F90 Competition: +100–130 wheel hp. Stage 2 with downpipes + intake + flex fuel: +200–250 wheel hp.
Do I need bigger turbos for 900+?
Stock turbos are good to about 900 wheel hp with proper supporting mods. Past that, upgraded turbos + built engine is the path.
How long does the M5 appointment take?
Stage 1: 2–3 hours. Stage 2 with mods to install: half-day to full day.
