Toyota Supra Mk5 tune. Nashville.
The B58 3.0 turbo in the Mk5 Supra (and BMW Z4 M40i, M240i, M340i) is one of the most aggressively tune-responsive single-turbo straight-six platforms ever produced. Stage 1 alone picks up 80+ wheel hp on stock turbo + 93 octane. Built turbo + E85 builds run 700+ wheel hp.
Every Carma tune includes.
Real prices, no dyno-number runaround. Here's what comes with every flash — at no extra charge.
What we do for the supra mk5.
Stage 1 unlocks boost, timing, and fueling across the B58's broad envelope. The platform is conservatively tuned from the factory — there's real headroom on 93 octane and dramatic headroom on E85. Built turbo + port injection + E85 territory is where the platform shows its ceiling.

Common questions.
Will Toyota detect the tune?
Some Mk5 ECUs log boost events. Free stock-revert before any planned dealer visit.
Stock turbo limit?
Stock turbo is good to ~500 wheel hp on Stage 2 + supporting mods. Past that, hybrid or upgrade turbo is the path.
ZF8 — does the transmission hold up?
Yes for Stage 1 and Stage 2 power. Past 600 wheel hp we recommend TCM tune in addition.
How long does the Supra appointment take?
Stage 1: 2 hours. Stage 2 with mods to install: half-day to full day.
