What’s your definition of “Stage 2”?

In the US, our tuners that use Cobb software (Dizzy, Stratified, Tune+, etc) here basically say the only vital thing actually required for a “stage 2” tune is an intercooler, and maybe regapped spark plugs.

Everything else is nice to haves, quality of life (like RMM), or candy with a little more “oomph” Where stage 2 is defined as “intercooler and whatever else you want, or nothing but with stock turbo and stock fuel.

What you have on the car is fine for Stage 1, add an intercooler for Stage 2, everything else optional.

Basically some other stuff is good to have and may squeak out a little extra power (intakes, crossover, etc etc) but there’s nothing else that’s actually required to run the tune safely. The 1.6 Ecoboost can basically adapt to anything else.

Are the plugs gapped larger or small than stock?

The support staff at Cobb are saying that a full intake is required for the Stage 2 OTS maps

Gap is slightly smaller than stock. 0.030” is stock, 0.028” is sufficient for a stage 2. Smaller gaps are only needed with upgraded turbos and higher boost. You can even regap them yourself with a spark plug tool.

You can run Cobb Stage 2 and even their old Stage 3 maps safely with nothing but the intercooler and plugs - the Cobb tunes are extremely conservative, unless maybe you live at high altitude. I’ve run both and never seen the OAR budge once.

The Ecoboost ECU is remarkably adaptive - the Dizzy and Stratified tunes are more aggressive than any of the Cobb tunes and yet are still fine with only those mods, per their recommendations.

Cobb told me that without the intake you should just run a stage 1 map, even with an intercooler. I’m skeptical of this but that’s what they said.

Replace your paper air filter with a washable foam or oiled (K&N style) filter and call it a day!
