Hi djvkool, welcome to coffeesnobs!
1. You're under-dosing! Put more coffee in the filter basket by adjusting to 'more' with the amount adjustment. With the correct dose, the metal line on the edge of the tamper should be visible all the way round the basket when you tamp with about 15kg 'force'. Search the forum (top RH corner) for 'five cent test' as a further guide to the correct dose. Also when you remove the portafilter there should be a slight imprint of the shower screen on the top of your puck, and the puck should come out in one firm piece when you knock it out.
2. Your grind is possibly too course, but get the dose right first, then adjust the grind to get 30ml in 25 to 30 secs, or 60ml in 25 to 30 secs with the double basket. If you haven't adjusted the pre-infusion away from 7 secs yet, that will mean 32 to 37 secs on the shot clock. If the pressure gauge still isn't hitting 9 bar, don't worry too much, but if you've got enough coffee of the correct grind in the basket, you'll come pretty close.
Enjoy the journey!
