Whilst looking for a leak, I tightened one loose pipe which I thought was causing the issue, but it didn’t work, instead I found the car to be smoking when I rev it from what I think is the EGR area? Maybe someone could advise me thanks

I have what I think is a boost leak on my car, I tried to smoke test it yesterday but I believe I’ve not tested all the pipes as I couldn’t find a leak, can anyone guide me towards which pipes to test and what they think this noise is, it happens under load at around the 2k rev mark in every gear except 1st gear, the car now lacks power and sometimes feels abit jerky, thanks
