running higher boost will show up weak pipes so check that first

Check the coilpacks too.

All the re-map does is expose weak links which were there before the map, but you didn't notice because it was running low boost etc.  ;)

AUM's do have a known thirst for new coilpacks, however it'd be best to get it VAGCOM'd first.  ;)

What petrol did you have in the car?? remaps seem to need higher octane fuel than normal 95ron.

remaps are done to specific petrol octanes so I doubt it's that

Would a slight leak in one of the hoses cause any difference to MPG??

Post by: w0ffle on 06 January 2009, 15:16

I woudl think so, mine is much more thirsty that it was a few weeks ago!

I have a replacement hose though, and I am going to fit it tomorrow! yay!

Hello W0ffle,

I think a good throttle body clean and re-adaption should sort things out.

Ok, I finally got round to fitting the new breather hose and it was all very quick and easy. At the same time I fitted a Forge 007p and a pipercross panel filter.

I think my fuel consumption is now back to normal! and the car seems to pull a bit better, not really that noticable but no real complaints.

I am getting a little needle wobble and some dodgy running occationally when in a low gear and low in the rev range so i think i need to look at the n75 valve and the coilpacks.

Mine had a split in it, and after fixing it the car felt smoother and stronger. My MPG went up too. Thought £26 for the pipe was a steep though!  :sad:
