Hey I'm getting the hang on things now but I don't know exactly the best way to tune for best fuel usage. I am only asking because I don't want to mess something up! So basically what tables should I be tuning? MAF? What am I watching when logging STFT or LTFT? And how should I go about making adjustments once I've logged things and reviewed them? Also when logging what should I focus on ie MAF, STFT, LTFT, RPM, MPH, KR, Spark anything else? Right now I'm using a stock DHP bin on a 97 GTP and I like the settings BUT compared to stock I'm obviously burning more fuel and also when I hit like 40mph it kinda bogs down and when I hit the gas to actually move it throws it into boost and then I let off and I'm good which I'm sure isn't right.. Thanks for the help guys I appreciate it VERY much!
