What we do for the ecoboost.

We push boost intelligently across the RPM band, optimize timing, and unlock the safe headroom Ford left on the table. Stage 1 customers commonly see 380–400 wheel hp on stock turbo + intercooler. Stage 2 with bolt-ons + flex fuel pushes well past 450 with stock turbo.

Common questions.

How much can I make on the stock turbo?

Stage 1 on a stock car: 380–400 wheel hp. Stage 2 with IC + DP + intake + flex fuel: 460+ wheel hp. Above that you'll want a bigger turbo.

Do I need premium fuel?

93 octane minimum for any Stage 1 tune. E85 flex unlocks the safest power envelope on the platform — we strongly recommend it for sustained 400+ wheel hp builds.

Will the stock fuel system support Stage 2?

Stock pump + injectors are good to about 450 wheel hp on 93. Past that, port-injection or a meth kit is the next step.

How long does the appointment take?

Stage 1: 2 hours. Stage 2 with parts to install: half-day to full day depending on what's already installed.
