Working with a stock 5.3 in an 05 Silverado with K&N and magnaflow muffler, otherwise bone stock. 87 octane in PA. Drove with Zeitronix wideband via serial and saw 10.5 afr delivered while trying to do a burnout (dead-stop, 100Kpa). Truck was obviously gutless and didn't execute. Wasn't entirely sure why this much fuel was delivered, so I decided to isolate maf from ve and run an AutoVE per PDF to try and figure out if the issue was maf, ve, or hard-part related. It didn't make a whole lot of sense that it was a problem with the VE table, seeing as it's a totally stock truck, but in speed density, it was definitely commanding way too much fuel. After 11 different logs/adjustments, I pretty much raped 95 & 100 KPA of the B0101 to get the mixture where it belonged. The VE table didn't look good at all, but was delivering what was commanded and actually ran better despite the crappy approach. Didn't feel great about this, but returned to maf operation afterwards anyways to see if it was good, but it couldn't have been more off. Wondering if there is something huge that i'm missing or if i'm fighting myself. I've had success with tuning my 00 2500 6.0 and cammed 00 camaro but am really pulling my hair out over this one and am fearing it' something stupid that i've overlooked.
