Anyone else getting more boost with the colder weather? In the summer i was boosting 10psi. When it started getting cold aroung 50-60 degrees I started boosting 12psi. This morning it was 34 degrees and I got on it on my way to work and I was boosting 16 psi. Kind of scared me. Had to get out of it. Dont want to blow my motor.

 

Well colder air is more dense but a 6psi increase seems high. I would expect 1 or 2 psi tops. Maybe other who live in cold places will chime in. I'm still in shorts and flip flops

 

The most I have seen between 95 degrees and 10 is 2lbs. 6lbs- something else is going on.

 

any ideas on what it might be? Everything seems fine with my truck.

 

even when it gets down to the thirties here i have only gotten 2# increase.

 

Have you ever had any belt slip issues? I know they are common on the prochargers, if you are not tuned for it a extra 6psi can kill a engine real quick. Do you happen to have a scan of it.. I wouldnt do anymore wideopen pulls until it is straightened out. Did your butt o meter reflect the increased boost? Clogged Cats could contribute I would think but... I dont know

 

Just kinda shooting from the hip here, get some procharger guys in here.

 

I dont have a scan of it. I dont know about belt slippage. How do you know if you have belt slippage?

 

Also i do have any cats.

 

I can watch my boost gauge and see it slipping. It looks like it is having a seizure the way it goes up and down.
