Don't really care about fuel economy. Just want the car to perform. It response quicker and has better throttle response.

Put the bigger jet in the primary. I had the same problem. I have 190 in primary 's and 160 in the secondary's. My car bogged off the start and then picked up. Solved it by putting the bigger jets in the primarys. I run two carbs.

Have you checked your fuel pressure? Maybe pushing fuel past the needle somehow?
