330hp vortec crate motor running with a L31 intake and a 411 roadrunner pcm in a 96 s10 blazer. I am currently running 82psi for fuel pressure with a walbro fuel pump. I have got good fuel at wot around 12:1 and its currently setup for sd tune.
I keep getting knock retard 8*starting around 3500-4k. The motor has a solid lifter cam. Here's a copy of my program and a datalogg session. 5.7BLazer_sd.tunLS1B_0001.efi
