Overall timing is quite low - looks obvious that you are running low octane fuel.

Your lambda is still doing some strange things bouncing up and down.

Then add some Octane booster. My testing (which was quite extensive) found that the NOS race formulation (in the black and yellow bottle that lists the up to 70 point boost) actually makes a significant difference.

Further, as a fellow Canuck, I know it's available at any Canadian Tire for $17.

There is a HPFP seal that can fail and dump fuel into the head, it affects fuelling and eventually thins the oil out and kills the motor. Does your oil smell like fuel?  These motors are very octane sensitive, octane booster or watermeth are very beneficial at stage 2 level. High EGTs/pinging have a bad rep of killing ringlands on the BWA/CDL motors.

No my oil dose not smell like gas, but I'll check again, yes I know I could buy octane booster from candian tire east coast Canada here in New Brunswick. I'll try a bottle and see what happens as well

What I mean is that your lambda goes from 0.80 -> 0.70 -> 0.80 -> 0.70 and so on. This is not normal. Low octane would most likely cause it to go rich because of the KR and being further off from the optimal iginition angle. It would not cause it to bounce up and down like that IMO.

post lamfa map

Question is:
Is your lambda in the logs sh*t because of your tune or for some unknown reason?

Car was put away for the winter did some work to it, had to replace my catless downpipe the flex was broken in it, new front PCV new bank 1 pre cat and new post cat o2 sensor i did some log on my Lambda % and it looks like the lower the RPM the higher the lambda % seems to be, i did two logs, should my LAMFA map be lowed in the lower RPM for the Lambda % to go lower,

 spec are
3" catless dp
2.5" axle back
3" K&N Typhoon cold air intake
added vis stage 1 HPFP
have to install RS4 FPRV
these logs were done on Stock inner cooler and stock DV as i thought LTFT was still there due to boost leaks as i have none now.
