No idea how you are getting the same with stock intake, might be my location? I do know Cheyenne is at a higher elevation. Either way when I do switch back to take my truck in for maint it goes down..I have invested very little to be in denial. I won't say I know more about the internals of this truck more than anybody else, which isn't true, but for somebody to say what I am getting isn't an increase from what I had on before without even seeing it for themselfs doesn't make much sense to me.
I could care less what I run, if it looked good or if it was made by some bum in the street, of it works better than what I had on before to help me gain more MPG's I will run it and before I do, I will run a ton with and without.
Like I said in the svtoffroad forum, I tested this thing driving down to the springs and back, both OEM and this configuration..not just some cruise around the block, but each had their chance..
I will say the super 40 exhaust was a waste of money, cause I saw absolutely no gains with it at all..except for a better sounding exhaust.
Either way it doesn't matter cause it isn't like I'm trying to convince anybody to use it lol I'm perfectly fine being the only person running this, could care less.
