Hi Guys, Over the next few weeks I'm having a bit of a tinker with my car and I'll be documenting the process for future reference. Because of this I need a bit of advice on a few things. As I'm having the car remapped and I'm looking to start with the best possible hardware set up before I go tweaking the electronics. EGR Delete What benefits will I see (if any) from deleting the EGR and what is necessary to carry out the job. Is the "A01" kit here all I'd need. DPF Delete Do the MK1 Leon Cupra TDIs have a DPF? I've found lots of people doing it to the MK2 but nothing on the Mk1 so far. As well as the above I'll also be doing the following: Mufflerectomy Removing the back box and replacing it with a straight through 2.5" pipe and tip with before and after power runs to see if there are any gains to be had by performing this cheap and fabled mod. Standard airbox and filter, uprated panel filter and an open cone filter I'll be comparing all three (before the mufflerectomy) to see if there are any gains to be had by 'upgrading' from a standard paper filter. Remap I'll then be remapping the car after we've achieved the most gains from the mods described above. I'm still running the standard clutch and so the map won't be an aggressive one, rather a tune that makes the car pull harder in gear - especially third and fourth. Eibach B12 Sportline kit, Pro-Spacers and Anti-Roll kit I have a full Eibach suspension set up coming over from Germany that comprises of Bilstein dampers, Sportline springs, Pro-Spacers and front and rear anti-roll bars. This should leave me with a well rounded, economical daily driver with a bit of grunt and nice handling...now we'll just wait and see the results! I'm expecting to see around 180bhp from the above and I could go even further (220-240bhp) by adding a Sachs clutch and DMF, hybrid turbo, hard pipes and bigger FMIC but for now I'm just looking at getting as much power as I can from cheap and simple mods.
