hi there ..
short story i got a 2007 300c with full na mods includes big cam and srt ported heads and ported manifold etc .
now i got a nice tune on it but when i do D or R with brake or without i mean when its idle low with no pedal touch the car start leaning by it self from normal to 19 and the engine shut by it self .
but when i use pedal every thing is good .. idk why it leans by it self gradually if i didnt use pedal and that is so bad specially when it die at signal red or in corner or a street hump .
notice that if i just keep the pedal or pot it in P or N it dosnt gradually lean or shut .
so plz help me out where can i do a fix on this on the tune
thanks .
