hi all
I had a 2003 1.9tdi a4 but i have now sold this and bought an A4 B7 2.0 tdi. Its lacking some power, i think, once you get up to around 100km/h. I would like to get this close to 200bhp. I am looking for information on things i can do such as :
1. info on bigger turbos
2. intercoolers
3. injectors
4 and then then programming the ecu to make the best of these mods. All help is much appreciated. Thank you ! love the forum !!

 

check out apr tuning, gonna be costly no matter what you do thou

the 2008 model should come from the factory with 200 horsepower, if you think the car is lacking, check the usual maintenance stuff like spark plugs and filters and ****

 

It's a TDI.

I've been here for about 5 years and there never seems to be a lot of TDI posts here. You might try a more dedicated VW TDI forum.

 

oh my bad, i didnt know there was a diesel option for the b7s in America.... but i guess the km/h shoulda been a signal lol
