i think at 10lbs it does make that it comes with a roush tune and bigger injectors but no fuel pump which is weird..but his charger is only boostin 7lbs right now i guess a smaller pulley will come after he gets tuned for real

 

I would not be surprised it he makes over 500 to the wheels if he gets a real tune, they are just figuring out how to tune those 5.0l DI variable valve engines it seems like.

 

true story...when grody first installed the charger and used the roush tune it wasnt makin any real power they had to send the pcm back to roush..they were even gonna send a roush tech out to posibly tune it on a dyno but it seemed to run alot better after the second tune...supposedly hes one of the first roushcharged 5.0s in ca he's gonna have powertrain dynamics in HB tune it once the xpipe and mufflers are installed

 

I really would like to do some runs with this guy

 

told him about ur z..said he"ll let me know before teh weekend

 

It doesn't say 550 RWHP though, it says brings the "Engine" up to 550hp and 470tq. Big difference. But I agree that with a better tune he can get closer to 500 at the wheels.

 

I'll run the guy from a dig on motor as well...
