I've lived all over mesquite and garland, went to school in Dallas though. Yeah the e30 tune is cool, allows for mean best torque according to stratified, maximizing boost and timing. I want a full e85 tune but that requires upgraded HPFP, LPFP new fuel lines and Injectors, which would run me 4k, so not worth it currently. Also ethanol runs cooler than regular gas, cheaper too.
