Boost 2015 XJ Lwb diesel
XJ L 2015 diesel; can the engine power be boosted? It's already chipped. I want to be able to out-accelerate a BMW M3.
I took it down at top speed with plenty of road ahead (it seems to peter out around 120mph) but it out performs me for rapid acceleration even in sports mode with the Dynamic switched to On)

@JagV8
Since my top speed beats his, I need only shave off a couple of seconds in a drag race. I don't need to outpace him, but I need to stay close behind until I get open road ahead of me—then he's dust. I'm wondering if a chipped petrol Portfolio would do it? I'm assuming an autobiography might do it out-of-the-box.
Thanks for your reponse, anyway.
