Well with the heat the way it has been here in delaware in the mid 90's with 75% humidity i decided to pull my car into my shop and check the a/c systems charge...i thought that it wasnt blowing that cold so i recoverd the system and did a leak test and ran a vaccum threw the system all is well right? Wrong i found that i only recoverd about 3/4 of a lb of freon when the car should have had 1.1lb. so i recharged it to the proper spec with no leaks in the system and now i must say this bad boy gets nipply now boys all i can say is bring the heat...just thought i would share...
