I am working on my 2003 5.3 ECSB 4X4 Silverado, just installed a new Comp 265 cam (212/218 .522"/.529" on 114*) and had my factory #706 heads milled .025" for a SCR of 9.87:1.
I am still working on the VE and MAF tables (armed with the Greg Banish DVD's) and for the most part, it runs pretty well for a first timer with only a few hours of tuning under my belt.
My problem is that when I have a steady state load (going up a long hill for example) with RPM's between 2k and 3k and 50% TPS, it seems to have no power. Checked the LOG and it looks like timing is being yanked (from 25* to 3*, frames 1150 - 1200 in the LOG) and I cannot figure out why.
I previously had an issue with knock and adjusted the timing tables to eliminate this but the KR does not seem to be the cause. I know its probably a simple answer (thinking burst knock form what I have been reading) but am not familiar enough with this yet. I thought about modifying the PE tables a little more, but don't think PE should be that easy to enter from cruise mode, if that makes sense.
I am including the LOG, tune I have been working on, and the stock tune for comparison. Thanks in advance for the help!
