need more power out of this Weber 48IDA

first thing first... I love this carb! way better than that stock injection. the only thing is i dont exactly know how to tune them. what size jets to use, blah blah. you can call me a carburetor NOOB
well as of know im running an stock SE motor and i know that its not tuned right. my low end SUCKKSS! ive driven a 12a that felt faster than my car. Today I took the carb apart together to clean it and change the gaskets.
this is what is in it: 180 air corrector,F8 emulsion tube, 190 main jet, and for the air, 120 jet holder with 70f10. 37mm chokes i think

what do you recommend i change? bigger main jet and f11 emulsion tube?

I'd also have to say boost. I just helped percent do a blow through on his 45DCOE and it really is shocking how much it woke the car up at low revs.

37mm chokes seem small... and exhaust is important too.

I drove Percents car before I moved and god damn it pulls hard. The F8 e0tube is going to be too rich for a stock port 13b. try the F-11's again. check your float level. All the tuning of these carbs starts there. if your float is off nothing anyone tells you is going to matter.
