I've noticed that after acceleration, if I snap the throttle blade closed, the engine will stumble, cut out, etc. It has never died doing this, and obviously, I can avoid it for sure. I would just like to see if it's a big deal, or perhaps if someone even knows why it does this. I have searched around on this forum, and found some mixed opinions in some threads of yester-year. Perhaps a blow off valve would help, (I know, I know, nothing "ricey", but the benefits to the turbo are palpable). It is a 1987 GN with a fresh engine on e85, trick flow 120lb injectors, 212/212 comp cam, ls1 maf, turbonetics 60 series, rjc fmic, g body parts 3" downpipe (internal wg), ported stock heads, currently on 20 lbs of boost (though it will do this after much less boost is made). My wideband shows 14.5-15 during light to no throttle, and will float up to 16 while coasting to a stop, 10 at wot. Anyone familiar with this? Thanks in advance.
