Hi, I know this has been bought up on here before, But is there any chips or aftermarket piggyback ecus available for the 4.8 autos to get even more power from the 4.8s ;) ,

If not how do we go turboing these ??

thanks

thanks for the info, holy !!!! thats alot of coin and alot of work.

is this really true, the 4.8 can only handle 5psi , i remember reading somewhere where there good for about 10psi constantly before anything has to be upgraded, providing their tuned properly?

not a cheap motor to play with by the sounds,

seems to be alot of upgrades available for the manual 4.8s but not the autos :confused:

thanks for help
