I have a question I was driving my truck to work today and I was only getting about 26psi of boost this morning at WOT. For the past ten days I have been getting up to like 39psi of boost at WOT but the temp. outside has been up in the mid 80's. This morning the temp. outside dropped down to like 34 out so is that why the boost dropped because the temp. outside got a lot colder? any information would be appreciated. Thanks in advance.
