Your sways killed you. Disconnect the front and try again.
Been there, done that.
Also, consider a tune, because something may have changed between the MAF and the fuel pump. It shouldn't, but you never know.
Your DA between the two runs was about 800-1000 feet more. It would have some effect, but not 3mph. Main thing is your sixty, which the sways are killing (I believe).

I have an L99 with Kooks Stepped Headers.CAI CAI w/scoop, and a JRE Tune. dyno'd at about 370whp/wtq. First time out was a few weeks ago and I ran a 13.1 at 109 with the stock Perellis. I couldn't get any traction in 1 or 2. all the nannies turned off and my 60ft were 2.1
Conditions: ~60* and 1200ft above sea level
So here come the changes:
Changed the MAF to a "strong" one (no retune)
Added Pfadt Subframe bushings, rear trailing arms, toe rods, front and rear sways, and differential bushings.
ZL1 fuel pump(no retune. This was prep work for the blower sitting in my garage)
Replica wheels matted to NT05R at 30 psi
Conditions last night: 75* and 1200ft above sea level
I got the Nittos nice and hot and with all the nannies turned off the best I could do is 13.4 at 106. Im not noticing any wheel spin and my 60ft times are around 2.3.
Do you think the temperature would play that much of a difference?! I was seriously hoping to be in the 12's with those Nittos.
I'm also thinking I need to be tuned again since I changed the pump and the MAF.
I guess it could always be track conditions... But I don't know! I need your help!!!
