I have tried Intelligentsia recommendation of 18 gram shot for 27 seconds. It tastes bitter. I have also played with reducing temperature till it turns sour. so this temp seems about right. I have tried coarser grounds as well so shots are at 23 seconds. I just cant seem to get the sweet spot. Any help would be appreciated.

My personal experience:
Before I changed baskets I was having a heck of a time pouring good shots. Using recommended 18g dose (I weigh each does and grind only 1 dose at a time) and my usual 40# tamp in a new curved style Nuova Simonelli double basket (which is below the ridgeline tamped.) Getting great ristretto shots (I like them better), 30 sec pour, all crema initially. After 1 minute of watching the "guiness effect" I get 1.5 oz liquid, ~ 0.5 oz crema. The roast dates I've used so far are Aug30, Sept 3. Not one bitter shot.
Have you been able to pour good shots with different coffees? How is your technique? Is the puck even? The recommended temperature is 198 F so you could try starting below and go up 1 deg at a time and stop when the shot is not bitter. Keep in mind I think when they recommend 198 F means at the brewhead, not in the cup.
