To anyone else reading this.....
Another thing to try is a battery disconnect. This will clear old fuel trims that sometimes are still there after the flashing of the pcm with a new tune.... Set your truck back to stock. Unplug Gryphon. Disconnect battery. Turn headlights on for 5-10 minutes. Turn headlights back off. Reconnect battery. Plug Gryphon back in. Drive 50-100 miles while at stock level. Then reload the tune.... In addition.... Clean your maf Clean your tb Change your fuel filter.....
