Noticed you speedometer is not hooked up, so every time you shift (TBS=% and speed = 0) you go into BLM cell 16 (idle fueling) this should not effect you dyno. This sounds backwards, and I can't really figure it out, but I did notice at record 171 your running out of fuel your injector duty cycle went past reliable operation at 86% and increased to 100% at record 179. That's not normal on a stock setup. Have you verified fuel pressure.. If tune is stock you should be starting out at around 11.9 AFR and then droping a bit lower to the 11.7 mark up through 4800 and then drop even lower after that. But nowhere near 10 at 4800. Mine hit 241 HP max when stock at about 5000.
