So who has ran the RCD 72mm turbo? My installer seems very leary on installing any oem charger with a bigger wheel in it. Another local reputable diesel shop gave him horror stories of having issues with them. It's already got tuning, dpf and doc delete, cac pipe, and an intake. It's getting a 4" downpipe, head studs, egr delete with elbow, new intercooler boots and clamps as mine are nearly shot plus fixing a leaking exhaust manifold. I just don't really want to put new stock chargers back on
