Hi,
I posted this out on ls1tech, but am just getting the advise of "get a tune". That's what I've tried Can you tell me what you think might be a problem to check for besides the tune portion? Thanks guys....should have come to you in the first place:
"Dyno, but what could be causing the A/F to show this? When I take off hard, there's no immediate tirespin, then at about 15/20 - this thing hits hard - it kills the 60' times eventhough on one of my better runs I had a reactin time of .108 (ok - not great, but not bad). Here's the graph - please follow link - http://www.geocities.com/tmarr11/file_3.bmp.
I know the image quality is poor - it was taken from a camera phone.....sorry - best I can do for now. Would appreciate what you have to say"
Take care.....and Happy New Year..
