Hello, I have a 2009 Silverado 5.3 LY5, dod delete, dod flow plate, ls6 springs/lifters, 216/220 .560/.560 lsa 114, high pressure melling oil, long tubes/cat delete, heads decked .20 due to overheating and stock injectors cleaned/flowed/balanced.
I thought I was starting to understand the VVE and MAF relations/spark timing etc and then Arizona decided it was done with summer and has dropped 20 degrees. I felt like I was getting close to the +/- 3% over all and now I am back to having misfires codes and deep colors on my data runs. Would it be worthwhile to scrub out the VVE/MAF and start fresh or would the cylinder bias/ECT be a better place to revise? Any help would be appreciated.
