The easiest and most basic way of doing it is to just disconnect the battery for around 5 minutes or so.

Disconnec the negative terminal of the battery and then hit the brake pedal until the 3rd brake light stops lighting up. That gets rid of the extra electrons floating in the system and then you can reconnect your battery and you know for sure its reset.

Best way is to get all codes physically erased, as some stored codes may not be erased by simply disconnecting the battery!

I was looking to erase the learning it has done in reguards to the fuel maps or whatever it learns. Basically have the PCM act like it would on a new car. I plan on running it through the rev range a few times when I get it back on the road.

Mother is not gonna let me gut it, and if she would let me do anything to it I would get one of those ADTR intakes

Its a good thing I don't live too close to you... Your mom might beat me up side the head for giving you ideas...

I decided to gut my filter box today just for the hell of it, and I'm shocked at the diffrence even removing the resonator inside the filter housing makes... Its really no louder than it was before but it sure does pull harder....

Now I think I know how those GP 3800'* went from 195HP to 200HP.... Does this mean I can say I have 210HP now
you know what'* funny? you do live near me I am only an hour or two from you

I have a pretty good idea where you are then.... Lol.. I'm like 30 miles east of Orlando... I hate driving through that place... Orlando drivers suck.. I like things a lot better on the west side of I75 though... Nice and open...

I live in titusville, thats about 10 minutes south of the Boonies.... And 40 miles north of a real city... Lol...
Cool, I'm going to be at the Peabody (spelling) in Orlando, from the 15th to the 18th
