When we last left ID Motorsports’ 2016 Focus RS project, the hot hatch had picked up over 30 horsepower and 46 lb-ft of torque courtesy of a custom tune and a Mountune cold-air intake. Since then, the company has opened up the exhaust and dialed in a more aggressive calibration with SCT Performance hardware and software.

Since we last check in on ID Motorsports’ 2016 Focus RS project car it gained a hotter tune and a high-flow Scorpion downpipe. These latest updates boosted the hot hatch’s performance by over 28 horsepower and 31 lb-ft of torque over the base ID 93-octane tune.

“We were happy with our initial results, but we always want more,” Matt Alderman of ID Motorsports explained. “So we started doing a ‘hot’ version of our Stage 1. Now we didn’t do the big torque spike as we found a serious drop in fuel pressure. So we decided to flatten out the horsepower at the end and carry it out.”

After refining the calibration, it was time to start reducing the exhaust backpressure to allow the turbocharged engine to produce power more efficiently. To do so, the company tracked down a high-flow downpipe that frees up the exhaust right behind the turbo.
