Ford Focus 1.5 diesel turbo zetec 2016

Scotty, my name is Andrew Parker i live over in England and own a little 1.5 turbo diesel ford focus from 2016. Its a great car in good shape with no codes. Im also a biker with a zrx1100 that ive worked on myself its never seen a shop and is going through some restoration. My Focus has no code no problems and no worries accept the slight lack of bite. Im of course aware its a 1.5l not a 3l v8 lol but was thinking about the stage 1 tune that takes her from 120bhp and 275nm torque to 150bhp and 333nm torque but wanted to ask your thoughts first. I dont want to ruin a perfectly good car but was looking to get a little more out of her. What do you think? P.s. great show watch you all the time great info and hope youve settle in well in your new stone house.
