No one mentioned or responded when the OP said he is cutting right now. If you are in a calorie deficit, you won't get much new growth. Focus on working the chest differently while you finish cutting down to where you want to be. Then to really make progress, you are going to have to eat more to feed the chest, and all your muscles, to get some new growth. Decide how long you want to have your abs, then make a game plan that you are over maintenence for 6 months at least. I don't mean overboard, just above 500 cals or so to start. Do a progressive addition of cals every couple weeks as you go. Once you get to your desired BF, track how many cals to maintaing that level of BF. When you can maintain it for a few weeks without weight changing, that should be your new maintenance cal level. You should be able to get a rebound type of effect when you add cals, since you have been in a deficit for a while. If you add the cals back slowly over time, you lessen the probability of adding too much BF in the process. If BF goes up more than planned, add in a bit more cardio to offset, but you still feed your body.
Really though, you seem to be pretty proportional all over, based on the lighting of your pic. You said you have tried everything, but how long have you stuck with a program? You should devote several months at least, I think 6, to the same type of program. Plan out a 6 month bulking phase after pretty boy season is over. Take some time off every 6-8 weeks to recharge, and stick with it. And don't plan a bunch of supp cycles either, just how much food you will need, and staple supps to help you grow. When you do add on size, all over, you will have earned it and should stick with you.
