You are running really lean and knocking in the upper rpm range. OMG You need to richen up your WOT settings. Also make sure you have your base set up correctly for your injectors.
 
what should i have my knobs set at on the MAFT the first is set at 0 the second 1 the third 0 and the fourth F.... I have stock injectors in my car
 
You need to set your Aux and base according t your injector size. I had to actually adjust my base up for larger injectors to get my cruise speed STFL and LTFL where they need to be at. See link for instructions

KI would not mess with the last know until you have the first three set properly. Set your WOT to zero and start logging from there after you have your base set (STFL and LTFL = 90%-100% for 1G)
 
idk if i have read that correctly but am i susposed to set the base knob at 2 with the stock injectors?
