No offense but 0-60mph in 4.2 sec is hardly impressive these days. Had a Porsche Macan Turbo that did that with ~ 475HP. Something is off if your car has ~ 750HP and can’t hook up on a launch to run low-mid 3.x sec 0-60mph. Anyhow, enjoy!
Btw - Dinan produces mediocre aftermarket tuning…super conservative, not aggressive for way too much $$. Before I had an AMG and GT-R, I was in the BMW tuning world but with an older 3-series. Wasn’t impressed with Dinan compared with other BMW tuning companies.
