I tried to install my AP today and it wouldn't work. i followed the instruction and ran the test. then i connected the initialization connector and began to run the installation. after saving my stock ECU setting and error message appeared show that i was only at 4.3 volts (it needs 11.7 to run the reflash). after retry numerous times i called cobb they think the doggle/noggle(sorry about the spelling) this is the part that connects into the obd-ll port that came w/ the AP may be bad. Chris at cobb told me to ask around if anybody in my area has a doggle i could use to see if this is the issue. I live in Fort Lauderdale Florida. If anybody has any suggestion or lives in the area please let me know. thanks.
