[QUOTE="texaslimeaide, post: 1504337, member: 6558"] Ok I may be crazy but have looked for this answer and can't find it anywhere. I've had my truck since new and it lost alot of weight about 60k miles ago. I have noticed that when the temperature is below freezing the turbo vanes cycle. Boost will go down to .45psi then after about 10 seconds of idling you can hear the vanes adjust and the boost goes to 1.45psi or so. When throttle is applied to leave the light it's instant response and runs just as good as always with no turning surge or anything. Once the temperature gets to about 34 degrees Fahrenheit the turbo doesn't cycle at all and at idle holds around 1.45 psi. Anyone know why I'm seeing this? Is it normal or is it something in the turbo telling me it's about to fail. Thanks for your thoughts! Sent from my Pixel 2 XL using Tapatalk [/QUOTE]
