Looking for a GHOST issue on my 2000L .
Built motor, Kennebell 2.3, pullied to 18-20#, EGR delete, 100shot dry nitrous, Turbo Blue, NGK TR6 plugs, etc.,etc... Reason I think I'm losing boost is that I previously (b-4 fix) had blown off my boost reference line from the blower and she just shut off. I was able to restart after a couple of minutes of cranking with no ill effects. Shutting down @ 3/4 track has the exact same feel as that blow off which makes me think it is the same issue??? Also, it only happens on a nitrous run which is controlled by MSD Window switch with all necessary tuning kicking in thru a flip chip @ WOT. Boost bypass seems to be functioning properly but obviously it's hard to observe at 100mph!! I'm thinkin about tee ing the boost bypass(dump) into the boost reference tube coming off the KB but I'm kinda thinkin it's not gonna change the top end boost. Any ideas floatin around out there about what I may be missing? Thanks for any experienced replies.
