Tunes are stock,50,75,100,140 & high idle. I noticed when I switch the chip between tunes a couple of things happen and I'm not sure they are normal?

Engine almost cuts out when switching at idle and the wait the start light comes on. These things happen every time I switch tunes while it's running? Is this normal???

Truck has no other issues besides the above.

 

I don't think that's normal... Might want to take the chip out and make sure the contacts on the PCM don't have any silicone left on them and also make sure your chip is seated fully...
