Watch COBB Tuning Trash Its Stage 3 EcoStang — New +80 HP Tuning Packages Released
Bring V8 performance to your EcoStang.
The 2015 Mustang S550 chassis is a massive leap in tech for Ford’s ponycar. We’ve written pages on the new independent rear suspension and that wonderful GT350 (and GT350R) 5.2L flat-plane crankshaft V8, but the 2.3L turbo four-cylinder (nicknamed EcoStang), the return of the SVO as some people lauded, has largely been ignored by the aftermarket. The GT’s 5.0 carried over from 2014 with only minor changes, meaning it was easy to support the good ol’ American V8 while the EcoBoost four-cylinder had to wait on R&D. That is, until someone from the turbo-four community came to the table.
COBB Tuning is new to the Mustang world, but the company has been a staple of the Subaru, Mazda, and BMW tuning communities for many years. It brings staged tuning packages, giving you correctly matched parts for your power goals, helping to ensure you won’t run into issues while cranking up the boost on your EcoStang. Additionally, the Access Port handheld tuner allows for tons of configurability with live gauges and additional laptop or PC-based tuning capabilities with COBB’s own Accesstuner Race software for custom tunes, offered separately on the Mustang packages to reduce price.
Each package builds on the lower one, so if you’re on a budget, you can just start with a basic, off-the-shelf tune with the Stage 1 handheld AccessPort package and work up to the more comprehensive Stage 3 intake, intercooler, exhaust, and downpipe upgrades.
Additionally, the AccessPort can handle data logging, and even integrates a selectable five-way map switch using the factory cruise control buttons.
COBB baselined the EcoStang at 255 hp and 299 lb-ft at the wheels. COBB shows that Stage 1 adds about 20 hp and 60 lb-ft of torque with just the COBB AccessPort and a panel filter; Stage 2 adds 65 hp and about 75 lb-ft over stock with COBB’s new EcoStang intercooler system and recommended cat-back exhaust; and Stage 3 finds a whopping 81 hp and 80 lb-ft of torque with a required turbo-back exhaust system.
Fairly substantial gains for a little four-banger—we might have to try one on our next rental Mustang.
