I have a 05 Pontiac gtp comp g recently just got it and I hooked my DHP tuner and it read the BIN file and let me save it just when I go to open the file on DHP or tinytuner it wont let me I get the ERROR#73 severity 1 I even tried doing it thru HXD and tried to replace the VIN like instructed and nothing it says access denied . I really wanted to tune this L32 but its got me going nuts even tried doing some BINs from the Drop Box and it says the vins aren't compatible ???
