Hey guys I've got some problems with my boost pressures, I bought my rig about a year ago and on the way home I managed to get 48 lbs at wot but I've noticed recently that I can barely build 42 lbs, I'm not sure were to do, I've changed my fuel filter and that didn't make a difference.. Any input will be greatly appreciated, thanks.

 

well in reality its not psi that makes power but the amount of air being flowed .... psi is a rating of restriction of flow ....

might wanna check CAC hoses and inspect you CAC to make sure its dosent have any cracks ...

 

Alright thanks, I'll see what I can find out, appreciate it.
