Reduce turbo lag on boondocker agility kit

[Dawson1223]

Was thinking of installing a vacuum check valve or something similar on charge tube to help reduce turbo lag. I can’t cut into the air box as my kit came with the intercooler installed in the air box. Looking for some ideas on what people have done with same air box. If you installed a vacuum check valve, what brand, crack pressure, and diameter of valve? If you used a reed where and how did you mount? Added photo of intercooler

Thx for the help

Been using a blowoff valve with weak spring and control line plumbed to engine side of throttle bodies. At idle and just off idle the valve is open to atmosphere creating a bypass. Closes instantly as throttle opens.
