Another thing to consider here is that you're at WOT on the dyno. Will the effect you're seeing at WOT at those RPMs (below 3200 rpm) affect real-world, part-throttle driving at those RPMs in the same manner? A dyno works great for finding max hp or torque at a given rpm, but isn't really a tool for part-throttle efficiency analysis.

I keep close track of MPG tank-to-tank, and I saw no noticeable change in MPG going from the stock intake to the Typhoon. I would be more willing to believe that anyone who sees a drop in MPG with an intake swap is using more go-pedal because he likes the sound of the new intake.

This is true, and I understand everything you've said. The question actually had come about by someone who's primary mileage is highway or greater. A small dip in mileage would probably have been tolerated, but he was looking at a 2+ mpg drop...a pretty noticeable change.

When someone states a mpg drop or increase, I am naturally a skeptic. Was the drop measured from just one tank, or was it an average drop after at least 3-4 tanks, compared to at least 3-4 tanks averaged prior, with identical driving habits, etc...

My primary mileage is highway (10-15% rural "city"), and my averages virtually didn't change with the intake swap. By "virtually" I mean that any small change I saw +/- were no different than how average MPG can fluctuate due to many factors.

I believe he said three tanks, with mainly cruise-control highway driving. After removing the Typhoon his mileage was back up within two tanks.

I had skepticism also, but I experienced the same thing with my Newmission mod. After having it on for a month or more, I still could not get over 30 mpg when my standard pre-Newmission was 32.5...

interesting... That almost makes me want to install the stock intake again to see what happens.

Almost.

It was over three tanks, almost 1000 miles of 90% highway on cruise. Frustrated the crap out of me, and within one tank I was back to where I was pre-SRI with the K&N drop-in.

Interesting that the removal of the newmission also allowed a second driver's mpg's to rise again.

Maybe the car just keeps resetting after a certain point, I don't know, but I do know that the car goes from feeling like a well-worn shoe on me and doing whatever I want to being persnickety and not responding in its usual manner, to all of a sudden being the car I love again.

ymmv.

Agreed. Drop in filter did the job. MPG increase and throttle response is better.

Sorry, my memory fails me something fierce...

I'm already seeing 1.5 mpg with the removal of the Newmission by the trip computer. I'm finally back over 30 mpg, so we'll see what the whole tank yields...

Sent from my stupid phone.

So does the drop in knn filter get better gas mileage? With out the snorkal delete and new missionn mods? Only "performance" upgrade I have is 2.25 piping flex pipe back with a magnaflow muffler "camaro" style(single in and dual out). I'm looking for an intake to work the the exhaust but keep atleast the same gas mileage or hopefully even better mileage. What intake would you guys recommend if any?
