Hi first post,. trying to figure out if I can tune over a pcm that's already been tuned with hp tuners using tuner pro - the project is my ZG Fairlane with a ford Cleveland running a LS1 0411 pcm, it's all up and running and had some tuning done already which it still needs more work but I'd like to look into tuning it myself - here's a video of it running before any tune work - I'd like to figure how to use tuner pro even if I need another pcm as I had Holley HP before and liked that alot tuning wise but all the hardware is pretty unreliable tbh so that's why I've changed to a factory pcm - cheers Jason
