Went to the track last night....
First time out with the new setup. I had everything pretty good tuning on the street from the EFI live scan tool, AEM wideband, and the sotp meter. I get to the track and on the first pass it spun just a little and pulled a 1.67 60'. I had to let out when I looked up at the wideband and seen an AFR of 15.5. 
That was 15.7 at 61mph. I added fuel for the next two passes but had to let out again b/c it was still really lean. Only made one full out pass with a little spin 1.71 60' and a 12.3 at 107mph . AFR was 14.1-14.2 with a bit of detonation and only 23* timing from knock retard. I really shouldn't have ran all out but I wanted to see if it would clear up since it runs perfect on the street. Forged pistons helped out there. 
Gonna see if I can find out why it's leaning out only from a dead stop with traction.
