The Verdict

Over the past few Test & Tune applications we’ve done here at DSPORT, it has become increasingly apparent that many bolt-on solutions require an engine management solution to be able to produce and retain significant power gains. As we approached STI T&T part 2 with this in mind, we were able to maximize the power available from the existing setup while maintaining the power gains over time. Stay tuned.
