[QUOTE="KCTurbos, post: 1061724, member: 13852"] I have a 6.0 with lots of fuel and have run just about every size vgt turbo out there... Not a 6.7 but i think it still applies. I was always told that vgts run with higher back pressure. So when I did my last build I put a waste gate on and set it to 60psi. I did that in an effort to try and help the turbo run more efficiently and save my headgaskets. I was not running a back pressure gauge at the time and never heard the gate dumping. So I installed a back pressure gauge and found out that I was not getting anywhere near the point of needing a gate. So... Tons of fuel... many different single vgt turbos... I never build more than 40-50psi of ebp and usually a 1:1 ebp/boost ratio at WOT (maybe 1.2:1 with a tiny turbo). No need for a gate in my case. It might be different on a single non-vgt. I know a bunch of guys running them and it seems that back pressure creeps up higher and is more of a problem when throwing a ton of fuel at it... especially with nitrous Hope that helps [/QUOTE]
