I'm the one wondering. Installed them on a customer's truck. Super happy with performance of the truck with the chargers installed. Drove it a total of about 75 miles with various driving styles to test performance. Absolutely amazing. Customer comes to pick it up and we go a 1/4 mile. Something seemed weird but we took off anyways. He gave it probably about 50-60% throttle, turbos spoiled and BOOM! Lower drivers side boot blew. Normally not a big deal right? Apparently I'm wrong. High pressure turbo seems to be blown (oil coming from comp housing outlet with intake removed on low pressure to rule out blow by tube putting excess oil residue in charger system). Truck is now also making a ticking. Also note, not my first 6.4 rodeo. Done this plenty of times. Never had one do this. Wondering if I got a Friday at 4:45 turbo......
