Hi, I have a 2003 2.0DTi 3dr black Astra SRi (Rare i believe )
I have fitted it with a K&N air filter and removed the lower pipe in the airbox, i have been looking at remap's (or a tuning box as it would seem with this engine)
Could anyone tell me if there are any risks involved with fitting it with a tuning box? (The car has done 148k on a motorway with full service history..)
And is there anything else that i can do? #i'm trying to get an exhaust system for it as changing the backbox on my old 1.7DTi did wonders, but, this has the 55mm exhaust system so finding one is rather impossible!
Any help would be much appreciated
