a standard tdci is about the same as a standard 2.2 :shock:
with a few minor tweaks - precat, exhaust, filter, the 2.2 will leave the tdci 🙂
but it's the same if you fitted a tuning box to the tdci it would leave the 2.2 :roll:
if you go full out on tweaking the 2.2 it will leave the tuned cdti 8)
I'm lucky enough to have both, so can compare like for like 🙂
