Bought this tester to quickly measure the backpressure on my 2003 F150 5.4L. The O2 sensors were seized, so this method of testing was critical. Just drilled a 5/32" hole ahead of the cat, plugged in the gauge, and fired it up. Drivers side had 15 psi at 2500rpm, passengers side ad 2 psi at 2500rpm. Replaced drivers side cats and got all of the lost power back!
