Maybe I didn't explain it very clear. It drops 2lbs. down to 56lbs. If you get on it hard enough it will drop to 54lbs. I didn't know if this was common or not.
At take off my motor is cutting out causing a bad shake. This would be above average take off. That is until it gets to about 1800 rpm and then it smooths out. I have no codes and I've got 58lbs. fuel pressure at idol and it drops about 2lbs. on take off. Any ideas would be appreciated.
