Supposedly some information leaked from a Ford employee saying that the new Mustang will not have a PCM chip insert, making it very hard for aftermarket tuning. Also, the car will have some kind of system that will not allow heavy fluctuation of torque levels. So if any aftermarket performance upgrades are made that effect torque, the PCM will act up some how.

Lastly, he said that the car will have the 4.6L rated at 300HP in GT trim, but the car is much heavier than the current one. Supposedly it will be slower through the quarter than the current Mach 1. Haha, just thought I would share. GTO for the 21st century baby!

well this is weird we just got back from looking at the 05 gt mustang at gary yoeamans ford in daytona its red it has red racing type seats and modern looking components no door handles its a drop top i think ?? they did not have any real info but a lot of people looking at it / i gave it a honest look and not for me?? ps the hood was shut so no looking at the engine/??

The new PCM will be based off a Motorola CPU .... pretty slick

chips suck, just flash the modified programming strait into the PCM ... GM's been this way for along time.

I cant wait to see the reaction of die hard Mustang fans. The people I have been talking to do not like the new Mustang.

I find it hard to believe that Ford would actively fight the aftermarket since it is HUGE for the Mustang. Sounds like another internet rumor to me.

You can flash the Mustang PCM now. Saleen flashed my PCM when I installed a supercharger. Rumor, rumors......

yes you CAN flash ford PCM's now .... hence the late model predators

BUT

they also use chips which are more popular

you can not install a chip into an LS1 PCM the same way

sorry I wasnt more clear

From what I understood was that the Mustang will not have a harness at all, so there is no easy access. Supposedly it's just like the new F150, but I haven't seen it, so i'm not really sure.

they all have ALDL ports .... thats where you access GM PCM's from
