Default fuel pressure question...

I recently had a Walbro Hi Output 340x in tank fuel pump installed. However, the fuel pressure is around 60 - 65psi and at start-up can jump to 70 psi. Are there problems with running high fuel pressure???

Thanks,

Ron

This is happening with the stock fuel regulator? If so, something seems amiss.

Those pumps will do that what does it run at off idle? Not much of an issue can play with the tunning a little.

its higher than stock.. not a bad thing unless your pulsewidth is bottoming out at idle.. your computer will adjust just fine otherwise.
