Caddy Ats owner needs help

Can't find much help at hp tuners or on caddy sites so figured would try the guys that really mod their cars.
I just did an oversized turbo and front mount on my 2013 Ats 2.0t and dunking into some tuning issues. Lots of knock even with backing the timing way down. Below stock. Is this common of larger turbos? It's not crazy just an oversized stock frame setup. Seems like my meth injection isn't helping at all. Wot 0 degrees advance even -1 and seeing up to 5 degrees knock somethings. Only thing I can come up with is trying a colder plug. Not sure if you guys use same plugs or not but going with an itv24 which is cold for my car. Any advice would be great. Thanks
