couple questions

long time mazdascenee.... anyway ive been in school and not paying attention but thinkin about how to make my truck go a bit faster
seeing that its an automatic i guess some engine mods would do..... i bought a shitty cavalier and now i can drive that while i work on my truck, so

i was wondering if their is a computer in the truck, im sure there is but where is it?
and if i can buy a chip? or a thing to plug in to my trucks comp to mess with all the stuff.
also was wondering of where to find a tutorial and step by step guide on how to take off the emissions system and put on a weber.
and one last thing a tutorial on changing the gear rations i think that since its rwd that the gears are in the pumpkin? if not then the tranny and how to make it so it has more torque

the computer is located if im not mistaken under the dash on the pass side of the truck and depending on the year it wouldnt mater because the chip does do much it runn some of the accessorys and such. there arnt many mods that you can do unless you do like turbo setups and engine swaps but mainly these engines are slow, you can put a webere and a header on it and get a little more hp. but all your doing when you do that is leting the engine breathe.

just my opinion
