that doesnt mean much. your visual test and butt dyno will never be able to tell you the difference. your MAF sensor will trick you.
James, I'm sorry to disagree with you as I have allot of respect for you. But my truck has zero smoke and it's dropping rail down to 24-25k on the big tune. Zero smoke on stock intake.
Dropping rail and no smoke, the 3794 is doing it's job well and so is the stock intake
Not saying there isn't more power to be had.
