If you take your numbers taken at SLC altitude (4,500 ft.) and multiply them by 1.16 you will see what your compression would be at sea level. Example 142 X 1.16 = 165.

There is a huge difference when you take into account elevation. 14.6 PSI at sea level is only 12.6 PSI in Salt Lake City.

Hang in there, those numbers aren't bad at all. How many miles on your motor? <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/kewl.gif" alt="" />
