1999 Firebird
I have a 99 firebird that we just did a turbo swap onto it and trying to use a tune file we found online for it but we paid to license the tune with HP Tunes. Stock file and that write file but keeping getting a failed issue.
Anyone have any insight on this issue?
All help and guidance is greatly appreciated.
I wouldn't just download a file and try to flash it in.
