what exactly is this. Ive been reading some peoples mods and alot of them have this. What is it and how much does it cost.

 

mopar made a performance computer for a while. they stopped making them in 98. if you want one you've gotta find one used

 

I bought one about a month ago. They might not still be in production but are still available. Mine was new or at least un-used.

thanks for the info, i checked out that site and it looks cool but i just dont have that kind of money to spend on that being im in school still.

 

Mopar performance computersorMP PCMs were made for 94-00 model years. Some years none were available for 4x4s V10s, or trucks intended for California.
Advances timing about 4degrees more than stock pcm, tweaks fuel a bit, removes mph limiter and raises rev limiter to 6000rpm locks out ac compressor under WOT and increases shift points to 5200rpms.Requiresyourun premium gas and should have a 180deg thermostat with one to reduce the chance of detonation that may occur from advancing the timing. (more prone on later model years)

Some Mopar online shops may still have some for certain years, ebay and forum parts for sale also good place to look.
