I seem to have solved my lean spike when shifting (or Ayousef did)...went back to my MAF tune. Details in this thread:
Next event will likely be the Texas Mile, but can't wait to get back on the 1/4 mile! Hoping to get 10.5.
I bought a 2010 SS Auto rear diff for the Mile (3.27), That will get me to 200mph in 5th gear...if I can get there...we'll see...
