I just recently bought my HP Tuners MPVI Pro, I am using my cousins truck as a guinea pig to try and learn. It was previously tuned by another tuner using HP tuners. I am going to add the .cfg and log later, I am still trying to learn to use it. Any advice is welcomed and step by step instructions would be most helpful.
Trying to fix spark advance and fine tune it a little better.
There is no low end power at WOT
A weird crackling noise almost like a backfire through the exhaust
