when under heavy load i can hear a squeeling noise over my spooling that im used to. sounds like a bearing in the turbo. egts jump way higher than normal saw 1600 ish on my edge programmer. has always run too hot to tow on cruise control. only making 21 lbs boost. truck has 140000mi. k&n intake that came with it. just did injectors, gaskets, studs, oil pump, egr delete, 5000 mi ago.
i know where to find another stock turbo with 50 thou miles on it. what is this used turbo worth? what can i do to it before i put it in to increase the life or performance of it?
or should i look into aftermarket turbo setups to get my egts lower? when switchbacking up the mountain pass or climbing a hill in the flat when towing i have to keep my eye on the egts to keep it under 1200 deg normally.
have never been able to make good power at the bottom, just chugs smoke massively. i was frozen down with my trailer and had to just keep it floored till it finally broke the ice free but the entire parking lot was in a black cloud. not the reputation i need in a state park.
