3.5 vs 3.5 HO
 

So I have noticed the concorde's and prob other chrysler vehicle's use the good ole 3.5 engine. i have noticed some are H.O (high output) giving them a bit more h/p anyone know what differences are done to the engine or exhaust to gain these horse's? not that i wanna attempt theses mods , im just a bit curious.

engine software in the computer and a tuning valve on the intake

sounds kinda easy? laptop and software?

nope u wont be able to upgrade the software like that

ok , im still stuck in the motorcycle days , recently had my last wreck a little over a year a ago , yea that kinda put the nail in the coffin. no insurance comp will insure me on a motorcycle. but anyway we would download software to the motorcycle's computer and free up a few more horses and pretty much change up the stock map.

cant do that in cars or u would change the federal emissions standard and they don't like u messing with there dirty air they are tying to clean up even though we here in the us are only 20% of the prob big brother will handle it all.

^ you my friend are the smart one. that big brother is always watching :(
