Is yours a DSG? Traction control on? I have an 18 SE FBO IS38 and the only time my tires squeal is when it shifts gears it chirps briefly.
Sorry for the slow reply, I've been super busy lately. That is with a DSG, traction control off and in sport mode. I can squeal them from a normal launch and do a squeal, squeal, chirp using launch control. I inflate them to about 36 PSI which I guess is a bit low.
