well, successful dyno trip, lots of interesting things happened let me try to get this all down without being confusing...
wideband has been showing up funny, just very jagged, and driving funny at times, like light cruise and under boost sometimes its lazy, breaking up, only shows an 11.50 or so, but sounds like its terribly rich.
first pull or two on the dyno, breaking up quite a bit.
ended up moving the wideband to where the factory narrow bands were. way up in the header, totally different air fuels, rolling into the gas pedal produces easy 10.0 submarine air fuels, after trimming it out, i got it to 480rwhp, at 12psi 12deg with stupid amounts of tq, i threw in 2 deg and it made 513rwhp.
now we figured everything is good, pulling clean, plenty of fuel, lets leave 12deg and go strait for some boost, hooked up shop air to a regulator and added 5psi to the tops of the gates, no change in boost, 10psi to the tops of the gates, 2psi of boost, right to 20 PSI on the tops of the wastegates made 4 more psi totalling 16psi...
it made 576rwhp 5000rpm and 800ftlbs of tq at 3000rpm.
so the turbos are totally done, and producing a TON of backpressure if i need to push on them that hard 20psi on top to make barely 4 psi of boost! crazy!
here is a pull on the rollers
i think i am going to totally change the turbo kit sadly, just not happy with the turbos, my oil return setup that has worked fine in the past is being a total whore also, tons of oil in the piping, under the truck, in the exhaust etc.
starting fresh, going to mount a gt45 i have laying around and see how she does up front.
