2014 Focus ST w/ JSTUNED E30 Tune Comparison
We had the opportunity to replace a customer's custom E30 E-Tune with our own version of an E30 Tune using our in house dyno for comparison. The car only picked up a few peak WHP, but over 30 lbs of peak torque and as much as 20-30whp and 20-30 tq pretty much everywhere in the RPM range! Gains were very noticeable behind the drivers seat!
