- 2016 Buick LaCrosse 3.6 Premium
I posted this in the Racing Forum, but haven't got a response. Has anyone gone to the effort and expense of getting a tune for the 3.6 V6? There is one from a company called Performance Programming that offers 15 more HP, improved (they say) gas mileage, and crisper shifting and takeoff. Of course we are talking about only 5% more HP -- so any other improvements would have to be really noticeable to justify $350. Anybody done that, or tried another tune company?
