Running an open dump pipe

Protected Freedom for 27 years! Thank a Veteran!
I have tried racing my GN with an open dump pipe and it cuts out at half track. Runs fine capped. Is this normal? Should I run it open? What do I need to do to run it open on the track? Thanks for your time!

Sounds like its pulling timing.... I hope you have a scan tool with thoose mods can you post a direct scan file or t-link file so we can see it or atleast give us some more info.... Sounds alot like its either runing outta fuel or pulling timing because of the dump :confused:
