Plugs were changed 8K miles ago but coils and injectors were not, car has 56k miles.
The runs are 1st gear, 2nd gear, and then 3rd gear. You see a dip in the boost for 1st gear because traction control kicked in and I lost power momentarily.
But could someone tell me if this looks good or bad?
Also, no issues with the car. But I do feel that like at 5800rpm or so, there is this "KICK" that occurs and it pulls to redline much better than stock. It looks like cylinder 4 had a -7.5 degree timing pull, the worst. Cylinder 1 had -3.5 degrees pulled twice. Cylinder 6 had -4 degrees pulled once. Cylinder 5 pulled around -3.5 degrees.

This log is pretty busy for me, read this thread and then post some csv logs in 3rd gear WOT. Be safe,

ACN 91 is 91 octane, Arizona California Nevada standards. Running sport is probably ok with these cold temps, but once warmer conditions come back the IATs will be high and begin to pull timing. Log to be sure, us Cali folks can't run aggressive tunes because of our access to fuel. But there are ways around that with pro tuning or adding higher octane such as purchasing 93, 100 or even adding 3 gallons of E85 to 13 gallons of 91 roughly 20% E85 pump.
A rule of thumb for timing corrections is 3.38 across 3 or less cyl is usually ok. But log to be sure and post.
