Hi, I'm new to the forum and pretty new to Audis too. I've had a B5 A4 Tdi before but now I have a 1999 1.8T Quattro Sport. I bought the car as I'd heard quite a lot about the engine's tuneability and I've ssen loads of magazines with 350bhp+ 1.8Ts in them. I'm no stranger to modding and have tuned a couple of Imprezas to around the 400bhp mark. So, I rang a well known VAG tuner last week to see what was on offer and was told there was "little or nothing they could do for the car"! I've read a lot of threads on various forums about KO4s upgrades and the like and getting low 200s out of these cars sounds easy, but I'm after around 300bhp and 300lbsft at least and there seems little or no detailed information about what's involved. Obviously I need to cover the basics first, exhaust, intake, front mount intercooler etc but if you are looking at big turbo and injectors and remapping there seems to be not much available from the tuning websites, particularly in the UK. Getting 280 out of a TT seems a simple matter fo a chip change so why the issues with the A4 Quattro? Any help would be appreciated!
