So, when is it not safe to turn these off. I get P1238 all the time with Garrett turbo and so far we were unsuccessful with trying to tune it out. My car goes into limp mode and then idles like on 3 cylinders. It takes 5-6 restarts to have it back on in normal mode, until the next time this CEL goes on.

Ok I played all day Friday moving tables around logging data identifying which tables are active and which are not. How to instantly set a 1238 and throw the car into limp mode. SO the good news is i put in a tune that would instantly set the 1238 and limp without even getting out of 1st gear well I have been pushing our shop car now for a couple hours and no limp at all no code either. Looks like we have a fix. I am just going to need to try a nice long straight away and see what happens. The only thing that gives any issue at all is launch control. The car will sit in launch control nicely for about 2 secs and then flare up to redline and slowly come down. Not the best thing you want happenning.

I used to be able to ride the stutter for several seconds without any issue when temps were in the 60's at the drag strip, but in the 90's at the shootout I ran 4 passes and on the 5th it triggered the limp mode for the airflow tables, likely claiming not enough flow for the Throttle position. It was odd that as soon as I lowered my torque limits tables a little lower to similar levels of the airflow limits it switched over to throwing the torque limits limp mode now.

Sorry if I wasn't clear but yes I have done the disables and no ocdes at all just having trouble with the launch control as it will flare up to redline and then slowly come back not sure what is going on there.
