I'm trying to decide the best option to choose between the ECU flash or a power commander. I'm running cobra tri-oval slip ons and stock air filter on a 2011 Vaquero. I see that people are in favor of both options, but I couldn't find anything that said which is best. The main reason I'm looking is to get rid of the deceleration popping and decrease the sluggish reaction. Any advice is greatly appreciated.
