I know this topic has been flogged to death, but I have just purchased a 1.8 TFSI avant and NEED some more grunt. I'd previously had a 2.0 TDI B7 which actually felt quicker. I have had a look through the forum but can't quite find the answers I need.
Now I realise the first place to start is a remap but there is so much discrepancy between the different tuners I am a little lost. As I understand it the extra power is coming from the additional boost, with the timing and fuelling adjusted to match. None of the tuners seem willing to answer my questions about how much boost they run, and if they are maxing out the injectors etc. Seems like reasonable enough questions to ask.
Given this is predominently a family car, I want it to remain reliable.
So my question is, where should I take it? I see remaps available from £150 - £500 for a Revo map. Why the disparity in cost? They're all doing the same thing at the end of the day surely? Also, Revo, Celtic Tuning and APR all claim the best part of 220 Bhp which is 10 - 15 more than everyone else. How do they achieve that, and is it safe?
Also is it worth fitting a performance panel filter or is the standard induction perfectly adequate?
As for other bolt ons I am struggling. I can't find anywhere that supplies FMICs, and decat/performance cats seem non existent for this model. The only other option I can see is a Milltek cat back exhaust, but I can't see the value in spending £1200 there.
Any ideas and feedback would be very welcome.
