It’s fast, but shoulda done it a bit quicker than that. I have a 2020 stx 2.7. 0-60 in 6.4s and 0-80 in 7.9s. Clear out your trans adaptive learning tables and let it relearn the shift points.
@@wyattolivier4087 I use the elm27 obd2 to usb adapters and the Forscan software on laptop. Software is free. You just have to request activation code every 6 months to keep it current. The readme file in download will walk you through the activation process. Also check to make sure which elm to usb or elm Bluetooth is compatible with your truck. The one I use was purchased a few years back when I had a 2011. It gives a ‘may not be 100% compatible’ message when I connect to my 2020. Once you get software working, the clear trans adaptive learning option is under the programming section in the left column. Then 2nd or third option in drop down list. It might drive like crap for a day until it’s relearns all the shift points. Cold air intake will help tremendously with the hard shift issues, and the high rpm issues when you go to pass at highway speeds. Mine used to hang up in 4th gear and sometimes cut out completely. The engine can’t get enough air from the stock filter, and throws the whole system off.
I just put new brake pads on rear, new spark plugs, cold air intake, and cleaned the 3 sensors on intake. Went from 14.7AvgMPG to 23.4avgMPG. I have a bad O2 sensor on bank 2 CAT I need to address as well.
