You might want to check your computer with a scanner to see what's going on in there. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I talked with Hypertech and wrote LS1Edit guys. If you don't run power programming with the PPIII you are fine. On the other hand LS1Edit lets you handle any probs with the GMS MAF and does everthing the PPIII does and then some. I'm selling my PPIII to get LS1Edit. I will test with the MAF then determine if I will sell it too. Once I test I will post results.
