vdrumright Posted November 8, 2004 Report Share Posted November 8, 2004 I got the radix all installed and love it. I have the normal rpm increase at start-up that I have read about on here and know that it will go away. What I am also experiencing is a fluxiation in rpm when it is in park and idling. It goes from normal idle to @ 1,000 rpm up & down. It's a up and down thing. Anyone else see or notice this? If not, anyone got an idea why it's doing it?

BSER Posted November 8, 2004 Report Share Posted November 8, 2004 never had that issue Vince. It may just be the PCM learning the new set up. You using a custom tune or the superchips programer that came with it? Quote Link to comment Share on other sites More sharing options...

vdrumright Posted November 8, 2004 Author Report Share Posted November 8, 2004 (edited) Still waiting on the tune. Brian said that my existing tune is close enough to drive it safely though.

Does't do it when I'm in drive. Quote Link to comment Share on other sites More sharing options...
vdrumright Posted November 8, 2004 Author Report Share Posted November 8, 2004 It's fixed. I put a new throttle body gasket in it and that corrected it. Quote Link to comment Share on other sites More sharing options...

dcairns Posted November 8, 2004 Report Share Posted November 8, 2004 Did you apply the tune that MagnaCharger gives you? Running the stock tune might give weird results, even if it works ok for gentle use. <edit> Never mind, let this window sit open too long and missed the other comments and solution Quote Link to comment Share on other sites More sharing options...
