Installed a Rinehart 2:1 on my 07 DX with a K&N and a PCIII with a known good map for the setup. Bike will only rev up to 6,000 then cuts in and out continuously but still will gain RPM's if I stay in it. Tried another map, same problem. Took the programmer off completely cleared right up. Sent the PCIII back to dynojet, they inturn sent me another brand new unit, plugged it in and same problem. Checked codes tonite and came up with a P1004. Any ideas to solve this nightmare would be appreciated. Thanks in advance.
