What was the engine rpm and boost pressure when the EGT reached 1500°? I presume your observations were done with an empty truck. I am curious as to why the high EGT's. I always thought

That makes sense regarding the 9 cm2 housing and could very well be his problem. - John

Hey folks, been lingering around this forum for years. Best site for reliable info.
My truck: 2000 24V with 262K, Edge Comp Box(VP44 is Tapped), Airdog 150 Lift Pump, 4" Exhaust, S&B CAI, ATS 48RE(Don't Ask lol)
Upgrade parts in question: HE351CW and DAP VCO 7x0.009 Injectors. All on 265X75r16 tires.
Recently l purchased a used HE351CW off the marketplace for $50. It was in bad shape, I opted for a Spoologic billet cartridge instead of rebuilding. Along with the turbo, I purchased DAP VCO 7x.009 injectors to spin it.
Project went smooth besides the dozens of boost leaks giving me hell. Countless hours later, with all the boost leaks resolved, my EGTs are through the roof. 3 seconds at WOT nets me 1500+.
My first thought was too much fuel, but I can't top 32 PSI on the turbo and she barely smokes regardless of fuel level on my Comp Box. I thought I'd be able to spin 40+, not that I care too. The big caveat to all this; I'm running the turbo non-wastegated as the stock one wasn't functional. I have the flapper closed with steel cable and it seems very tight, but I'm aware this could be an issue.
I have gauges so I figured I'd turn fuel down or use mindful throttling to manage boost until I figured my wastegate solution.
I do plan on purchasing a spring wastegate, but this still isn't adding up for me. The truck runs great and I'd be content with the boost it's making if not for the EGTs.
Am I overlooking something or is boost potentially leaking by the flapper due to my silly solution?
Any advice or criticism would be greatly appreciated. Thanks in advance!
