You'll need to clean the OCV's, check/remove the banjo filter.
Listen to the turbo, learn how it sounds. If it begins to whine look at replacing it, before it starts to whistle which is just before it blows.
You'll also want to get a catless up pipe, and remove the EGT probe which requires the 2.2kohm resistor in the gray connector the probe came out of.
You may also want to get a tune, because there is a flaw in the OEM MAP that can cause burnt valves.
Then if your going that far, might as will do the DP and get the full benefit of the tune.
