I don't understand how he is saying I gained 150 by going corn?... The tune it had previous to going to Shaun was a Crappy tune, the graph was very shitty, car ran like shit and had a stuttery throttle response. After it was dialed in on 91 it made 718 STD, and switching to corn it made 784 but ran out of fuel. So it wasn't a 150hp gain. It was 66 gain, which is just shy of 10%. So someone needs to go back to school and retake math before coming in and talking shit on my car and the person I chose to tune it.
