now stock file again cat tests per trip stock is 18

Thanks for the information... BUT

1) This only works if TinyTuner supports the OS that is in your PCM

2) You can only use TinyTuner to edit .bin files, it won't edit HP Tuners' .hpt files; and I have yet to find a file converter app that will convert a .hpt file over to a .bin file.
