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!
