As avove it looks lean likely causing knock
Good set of parameters to log is
Engine Speed (rpm)
Throttle (percent)
MAF Voltage (volts)
Engine Load (g/rev)
Ignition Advance / Total Timing (degrees)
AFR
Commanded AFR / Target AFR
STFT (percent)
LTFT (percent)
Oil Temp (F)
CL/OL / Fuel Sys Status (2 = CL, 4 = OL)
IAT / Intake Air Temp (F)
IAM / Ignition Advance Multiplier
FLKC / Fine Learning Knock Correction (degrees)
Its also a little strange your ltft is always zero , was this log done imediatly after flash ? Or have you disabled ltft
What are your end goals ?
The three mods you mention
Craford blocks
Intake
Throttle body
Wont trealy help you much but will cost you a lot
NA you wsnt a good catless header and exhaust
Tune
Or tunefor e85 fuel or flex tune will be best bang for buck
Craford block work on stock cars but on runed cars you can get similar results with cam riming adjustments
Throttle body not rearly needed stock one flows well
Same with intakes very minimal gains
The supploed perrin scaling is not that great and will usually require further adjustment
