NateZ Posted October 31, 2004 Report Share Posted October 31, 2004 Is it true that you have to disconnect the air bypass valve on the whipple supercharger when using a pcm tune like nelson/pcmforless? If so.. then does that completely do away with thier whole thing about how it doesn't boost at highway speed and give good highway mpg etc etc?

Nate <{POST_SNAPBACK}> Hi, The emergency bypass that opens if the whipple computer loses power is the one that you have to disconnect by wiring the relay for it so it stays shut. Otherwise it will blow off all the boost. Thanks, Bryan Link to comment Share on other sites More sharing options...
