First off here are my current mods..... 3.4", 180 t-stat, 104s(new), 2.5 catted DP with u-bend and resonator delete, P-log, Custom DHP PCM. Anyways with the "standard" DHP PCM I was hitting as high as 10 degrees of KR. I know!!! So we dropped the timing back to stock. Still seeing as high as 6 degrees of KR. Added 10% more fueling and still getting bad KR. The IPWs are high as hell, 18 to 19 and the IDCs are as high as 90. Basically my injectors are maxed out if not beyond some. I replaced the front O2 to no avail. My LTFTs are around 7 and O2s are 900 to 910. I'm buying a wideband tomorrow and haven't gotten around to check fuel pressure yet. I guess I'm just looking for any ideas on what things to check. Thanks!
