yes, that reset should work for you. Also, you don't have to disconnect the battery to reset the pcm. You can pull the pcm fuse and turn the key on and off a couple times, then replace the fuse.

Did you recalibrate the speedo for the larger tires?

Sorry to hear the bigger tires took you by surprise. But not only do they hurt gas mileage but in my experience they also effect your braking distance. The big tires change the mechanical leverage the brakes were orignally designed for introducing a lot more heat more often. You might try an emergency stop from 60 mph to get an idea of how it now stops. Good luck..

Jammen- Nope, sure haven't. Would that really throw the mpg's off.....that much anyways?

Red- Whats happening my friend? They didn't really take me by surprise, I knew I'd lose something. More weight + larger rotating mass= gonna hurt somewhere. Just the laws of Physics I reckon.

I think I'm not so much frustrated with the tires causing the loss in mpg's, its more so the maintaince not helping, but actually hurting the situation. Like I said, I lost a mpg or so after the tireswap, and another 1-1.5 since the maintaince....

The one going from the airbox to the "air source", for lack of better term. It kinda curves toward the radiator, where the air comes in.

Im probably just gonna put the whole damn factory setup back in, see what that does. What I have rigged up in there is so retarded, its probably hurting more than helping, plus it looks like azz anyways.

Taking that little "snorkel tube" off made the intake howl when WOT, sounds real good, but I'm wondering if thats factoring into the equation somewhere
