Before getting my TD5 chipped......

Is there anything else I should do to ensure its running tip top?? I fitted a stainless centre box and it increased performance, and Ive just recieved my allisport egr removal kit which I will fit tomorrow, but the question is, is there anything else I should do first?? Ive heard about cleaning various sensors and the wastegate and stuff but not heard exactly what to do. anything you guys recommend?
thanks!

Twisted performance and td5 alive know plenty bout making landys go zoom.Id say get a v8.....

nahh mate I like my bank account plus my TD5 blows my mates 3.9 v8 all over the place standard! hehe
