ive just changed my pace intercooler for the new pace front mount in doing so the boost level has droped from 19 psi to 14 psi does any one know if it is safe to turn the boost back up to 19psi or will that make the car run lean thanks alot dave

 

I'd check to see if you've introduced any leaks into the system.. it shouldn't drop that much..

 

iam sure theres no air leaks as it hold 14 psi all the way up to the red line in in 3rd 4th and 5th gear. if there was a leak would the boost not drop right down

 

No, not necessarily..
