Deck Plate lowered my mileage...help
I have the deck plate modification and a K&N filter in my box. I noticed a drop in my gas mileage...any suggestions? Do I need to wall off my engine compartment so I'm not sucking in hot air? Would a Amsoil filter be better? Finally, should I unhook my mass air flow sensor? HELP

I know it sounds real cool when you stomp on the gas between 4k-5k rpm..but that is what is causing the lowered MPG... if you drive normal it will not be that bad.. I have a log of my milage and the first few tanks of gas was a lot lower ( I believe because the computer has to get used to it) and tha fact that it counded so damn cool to me
BTW, I am using the amsoil filter..not the K&N..I do not know it will make a differience..but I ma not an expert..I have never used the K&N

Like I said, I have never had a K&N..but I did have the amsoil for a couple of weeks before I put in my deckplate..and it was a world of differience over the stock filter...

This is sort of tangential, but what size deck-plates did you guys all go with? I recently bought a 4", have't gor around to installing tho. Was hoping for something bigger, but the next step up was "8.
I'm hoping to get it in tomorrow-wanna see how it helps on my up-coming cross country trip (already got the new exhaust on) mileage wise, if at all.

97'. I installed mine about 6 weeks ago and I've been averaging ~16-18 mpg street/fwy ever since. Not much of a chance from whence i didn't have the mod. Granted, I do floor my truck at every on-ramp just to hear the sound.

I go between 16.5-21 that is both before and after deckplate mod

About the same actually. I didn't see much difference in fuel consumption...
