Been running the BMW 3794 from Danville. Was a fun turbo for sure, but I am planning on pushing the truck harder in the near future so Mark bumped me up to his billet 72VGT. I am in love with this paired with my Danville billet 483. The spool and power curve is insane! This is my favorite setup to date for power vs driveability. If anyone is on the fence about this type setup, just do it you won't be dissapointed. Thanks again Mark for the new charger, couldn't be happier with it.
