Water-meth installation may be a little risky, considering I do not know what it will do to my new car warranty. But I am very happy that I did it! I drove a reliable, but boring Chevy Prism for 12 years before this, and I wanted this car to be fun. The tune was my number one performance improvement. The water-meth system and meth tune are just extra ridiculous fast. 190HP\/200TQ at 3100lbs. Who needs a Mustang, I have my mid-life crisis solved with a tuned Cruze!! :) \nAlso, as far as I can tell, none of these performance improvements have had any negative impact on my fuel economy. Well, perhaps the meth tune with the aggressive timing that is breathing and feeding the engine, may have less MPG when pushing it, but this is uncharted territory for a normal Cruze. MPG does not matter at WOT!\n\n\n\n\nForget about the warranty, this is the ONLY reason why i dont have it on my car right now, since i was one of the 1st that Brian proposed it to...\n\nIf s dealer see you with that red pipe pluged in your intake piping, the warranty is gone. :brave:\n\nBut its a very good system and for sure i'll do it in the futur.
