I have a 1997 A4 z28 with 111847 miles. I deleted the donkey dong on the elbow and all seems to be fine. However, my oil pressure gauge is reading really high all of the sudden. It previously read about 20psi. Since the mod, it now reads 40-60 psi when at idle. It does not move much during acceleration, leading me to believe that I may just have a faulty gauge. The gauge slowly falls back to 40 if it was reading 60 psi when I started the car, but it still seems high. It runs fine though so im confused.
