Boost spiking??
 

I have the following doubt:

Is it possible to get more spiking while cold? I mean, normal operating temperature, but on the first accelerations.......I mean, tonight was really cold outside, and I got higher peaks......not sure yet whether it was the temperature or my wastegate......

Also, should this be due to temperature, is it as dangerous as hot day spiking?

And last, should I trust the peak readings on my VAFC, I just cant drive and look at my boost gauge while doing 3rd gear runs........

Boost spikes are more dependent on what type of wastegate you have, not the weather. How high are the spikes?
