for many years I have been changing the way a motor runs. If yo want to in crease power and increase the way it accels. you need to add more fuel to the engine and you need to make the engine utilize the fuel better.
Camshafts, porting, carbs, headers, Manifolds. timing chains, pistons, rods, etc. and gearing
If you add more fuel to an engine that can't use it the damn thing just boggs down at low rpm, surges and stalls. amungst other things.
Now you have the computer world.
you can do some adjustments to timing, fuel mixtures, shift points, and various other items, gear ration, tire size, Etc. through the Programmer
this change adds the addition of more fuel a better way to fire it, and allows the use of higher rpms
not only can you make changes to the computer you can also make changes to the way the air comes into the engine spacers,throttle body, Cai, Blower, Nitrios, etc. ( Some Legal Some Not) The most comon is the CAI,
You can also make a chage to the way the burned fuel or exhaust leave the vehicle. changing the exhaust can relieve back pressure and a difference in power band
Cat back systems or headers
I live in california so I leave the cat in
noW I am getting lost in what I wanted to say!
minor mods do minor things to an engine. CAI and exhaust are a good start. but they are minor.
A programmer will get the most out of you CAI and Exhaust but the programmer won't work as well with out the CAI or Exhaust.
I have used the Programmer with only exhaust. it worked but with less of an increase.
Sorry if I let out to much garbage
