I finally got this installed inn my truck, It does actually spool decent, and i haven't even tried playing with the tuning yet, just run a base file for a non vgt from WPE. it'll make 5 psi @ 1500rpm, and slowly creep up and when she hits 2000 rpm she takes right off. It will take a while to adjust my driving style so i don't blow too much smoke. biggest difference is I gotta roll into it slower and once she lights. mash it. Compared to my barder stg #2 it does move more air top end, and generally less BP. As far a egt's go, i can still hit 1700F on a wot pull. just takes a little longer. Its not WAY faster but does pull harder. worth the swap? i still haven't decided. running 60mph it makes 3-4 psi @ 70mph 5-6 and 80mph 6-7psi. Max boost has been about 35psi. the ebp to boost ratios are close to 1:1 until you hit 30psi then ebp gets higher and goes out of range of the factory gauge highest reading I've seen is 38psi ebp. It actually is very similar in many aspects to the stg #2. biggest difference is more top end, obviously not instant boost like a vgt. and no turbine whistle. I doesn't completely cleanup my 190 30's but I'm mont holding icp like i should i can actually feel the truck surge ahead if i back off the throttle and shorten PW with my foot then icp increases and truck feels much stronger @ 1.8-2 ms pw. I plan to ditch my rcd pump and try a diesel site.
