I am really stuck on this and pulling my hair...
I have been driving 320D(177 BHP), and decided to change my car. Looked at the deals, and 320Ds(New Shapes) are expensive, therefore, decided to go for a 2.0 A4 Sline(I got a nice deal and very low mileage). It is 60 plate.
the BHP on this is 141, and I think I will miss the performance and agility which I had in BMW. I had a look at the ECU re-mappings and seemed sensible to boost my performance with another 45 BHP(Maybe?) I have a few questions on this, if you could help me...
1) Does ECU remapping make any damage to engine in long term.
2) Does is hit MPG badly?
3) I am buying car from Audi Dealership, so it has warranty(1 year). if anything goes wrong(not necessarily due to re-map), will dealership be able to find out that ECU is remapped?
4) Do audi dealerships offer such service?(This might be a stupid question)
5) What is the max BHP I can get with remap(Safely)?
Many many thanks for helping me on this in advance.
