Default Help tune almost complete, few problems!!!!

I have been tuning in SD and have all my LTFT -2 to 0. I have a stock screened MAF on the car and wanted to know if I need to do any tuning to my MAF freq. I am also having a big problem with gas milage, Iam only getting around 15 mpg. I thought this might be because I was running really rich before the tune LTFT were -17/-20, but my fuel milage is still the same, most of my driving is on the highway so I dont think my converter is the cause of poor fuel milage because it stays locked all the time on the highway and I drive 60-65 so my rpms are 2000-2300. before the long tubes I was getting over 20mpg, any ideas on what to check would be great!

If it your tune is right, then I'd start checking mechanicals. When's the last time you replaced your fuel filter? Cleaned your air filter?
