Just bought an 03 Avalanche 6.2L black scorpion motor with a newer switch blade installed. Has the pad on the dash to adjust the position. The previous owners weren't much help to me as to how it functions and what kind of a difference it made.
According to the site, it claims to improve gas economy. Seems to me that it is going to kill it even in the neutral position. I'm also wondering what it's doing to my top end speed.
Can anyone attest to me what impacts it has that has used their boat before and after installed? I can't even get my boat up to 40mph, but maybe it never did get that high.
