You are WELCOME!! I will keep an eye out for the final tune results. 408's are the most fun to drive, great power band on them!!
We should have your other 408 done here very shortly.
Thanks

We picked a fairly tame Cam so I'm not expecting the huge #'s.I figure 530hp and 490tq when it's done. Chris,good to hear on the motor.We can't wait to pump 14lbs on Turbo into it

Don, what are Mullit wheels?? Did you mean Mallet? If they are Mullit wheels then they must be from back in the day when you were cruzing around listening to Iron Maiden or something
I never said I was Pimp 
. Just makes me want a 408 even more. Hopefully sooner than later
