Best thing i ever did to my regal. The power output was amazing. Running no Cats, with e85.

I love the performance increase and improved throttle response - for me this is the best HP/$ upgrade you can get for your vehicle! I also got the e85 calibration and the results are dramatic over the 93 Octane tune. I ran head to head with 93 octane vs another Regal running e85 and it pulled away with ease, forcing me to get the e85 calibration also :). I love that the tune also adapts to the octane rating if I cant find e85. All in all I HIGHLY recommend this product. I'm also a proud owner of a Trifecta tune on a Verano Turbo and can say every future vehicle of mine will have a trifecta tune (if available). Outstanding product support, easy installation and awesome performance increases. Say goodbye to stock.
