high rpm miss

[Sturdevant]

So, the lights flicker at high RPM's, or at other times?

[bobs turbo pt]

are the lights flicking under a load or all the time ??

I have this problem with the high rpm miss also, even with the stage 1 it still does it. It's basically like a dead spot.
Also does anyone have a rough idle on their cars? or a drop in idle rpm and then it goes back to normal?

now i am having problem with the lights flickering so finally i got them to change the PCM i got the problem with the high RPM figured out but the light thing is another issue for me now.

Try addding more ground straps. Go to AdvanceAuto, etc, they have pre-made "battery cables" of differeing lengths. Go from - of battery to engine block, housing of computer, and body. It can't hurt.

I had the high rpm miss, the Dealer changed the PCM which corrected most of it. I found that the iridium NGK plugs really helped, but gapped at .047. Others have had good results at .030, but I found that the GT liked the .047.Any more than that there was spark blow out, any less the performance dropped off. The GT seems to have a "sweet spot".
