fuel pressure too much?

[ferdtucks]

i installed a fpr shim kit about 2 weeks ago and i shimmed it to 70lbs well i went under the hood today and noticed at idle it was between 75-76lbs , what happen? anyways i was wondering why it jumped up like that? and if thats too much fuel pressure?

You'll be fine... Mine will vary from 67-75 from day to day... When the fuel filter starts going I see it drop to 60 or so...
