I'm just curious how much timing some of you are using at cruise speeds of around 70. At 70mph running about 2100rpm and I'm commonly in the 38º-40º of timing range with my own truck. I was just curious how high others are running?

 

mine shows to run about 34 degrees. also its commandind 15.3 AFR

 

ttt i want to see some others too

 

I'm usually in the 35* range at highway speed

 

Here are a couple of logs from my own truck on the highway. I have many other logs from Radix, Procharger, high compression, strokers, etc. I was just curious about this because I've asked some about this and get odd answers. Some have said they run 30 degrees like it was a high number and some others have told me that they get away with 40+ like high 30's is nothing. I know that this is a very load dependent thing, but I'm just curious to see what others have run or do run. I commonly shoot for 36+ for example on an SS awd Silverado. I have logged many that were set up for mid to high 20's and I'm just curious if this is a common thing and maybe I'm just out there.
