AFR question
I had my car dyno'd this weekend cause I was curious to see exactly where I'm at after the 272/272 cams and tune from Justin. It pulled 283 hp and 301 ft lbs in the initial run. He told me i'm running pretty rich (around 10:0). He made a quick adjustment with my SAFC and leaned it out to about 11:3 and it pulled 296 hp and 298 ft lbs. I told him thats great and all but I wanted it zeroed out because I didn't want it interfering with Justin's tune.
Now like I said in another thread I'm happy with the custom tune I got from Justin. Curiosity is getting the best of me. My question is which AFR sounds better to guys?
Would leaning it to 11:3 hurt anything or should I just leave it?
