have you made any headway on this problem? the programmer will not allow me to make any parameter changes. no speed limiter, no rev limit adjustments, just 87 or performance tune. this is on a 2003 silverado with a 4.8 L you said you need me to email the factory tune? what software will i need for this to work. im going to radio shack for cables an a power supply wednesday. im staring at a bunch of parts on the floor that i'd like to install, but i can't until this problem is either fixed, or i go have my pcm tuned at the speed shop.

thanks

Is this a standard Predator or an SLP unit?
What is the revision?

Thanks

i think it is a standard unit. the revision is 2.04. thanks.

Can you please post up your VIN so we can test this in house?

Thanks
