So your logging STFTs at 6100? that means that your commanded AFR is ~14.63, that is not really a wise idea IMO just a tad lean for the RPM....

It's chevy tough, it can dig it BTW I'm not under any load when I'm doing this. This is more less mid to light throttle. I need all my VE cells perfect as this truck is going to run in SD. No MAF for me. Also I'm not seeing any KR so I'm not worried. I can tell you right now though I'm going to have to install my 44 lb/hr injectors. I'm not even into PE yet and IDC is around 85% If I have time tonight I'll swap them out. Also I'm going to look at the grounds anyways even though I got the REP problem fixed. I am having a shitload of errors yet and the 02 readyness tests aren't completing. Grounds tonight, injectors another night. We'll get there. You guys just might have me eating crow, this 6.0 is getting stronger and stronger the more tuning I do it to. It's actually kind of dangerous to drive daily I think. The NV3500 is holding up fine and the clutch doesn't slip at all...........yet

Be careful with that NV3500, we have had alot of them drop 3rd gear out of them.

What's wrong with 3rd gear? I know people try speed shifting into 3rd and it grinds. I just shift it normal then gun it after the clutch is engaged.
