Ok, here's the situation. I have a stock LQ9 in a truck, only mod is ported heads and milled...10.6:1 compression. I bought EFI live several months ago and found out on logging that I was having massive KR at wot and my LTFTs were like 10%. I sent this to my tuner and he said I had an air leak somewhere. Fast forward to today I changed out my intake manifold gaskets and throttle body gasket. Logged after that, same thing. 7-8 degrees of KR at wot. We then added 2.5% to the VE table, and 5% to the MAF table below 5000hz and 15% to the table above 5000hz. My o2 readings are looking much more suitable (.900-.930mV at wot versus .750-.800mV before the changes) but I'm still getting the KR and now at WOT around 4500-5000 rpms the engine starts feeling like the power delivery is "wavey" and or slightly surging. I'm still wondering if I have an air leak or what was going on. I dont know what could be leaking. Other than the changes I made, I'm running a stock GM 2002 LQ4 tune. The first log I am attaching is from May, the next one is right after the gasket swap on the stock tune, and the final one is with the fueling changes. If I put the truck in 2nd gear and punch it from like 40, it seemed with the final changes that it pulled good with no KR, but it only does 14 degrees of timing? Whenever it tries to bump up to the high spark table, it instantly bursts 7-8 degrees of KR.
