After a custom tune by Trifecta Tunes, my 2.0 LHU went from 220 hp / 258 ft-lb to
300 hp / 330 ft-lb, so my Regal is a little sleeper. The car was so de-tuned it was crazy. The exact same motor/turbo/transmission in the Regal GS from the factory has 270 hp / 295 ft-lb

It is like a whole new engine is in there
