Marshall:
I did actually wonder if it was to do with air hitting the end of the pipes, but I tried moving them around a bit with no luck.
Also it doesn't explain why the noise happens on KO3 but never (very rarely) on KO4 when its the same pipe work.

Yeah I know exactly what your saying it strange why k03 cars are noisier than k04s
Doesn't help you though.

I dont think its a case of more power, its a case of engine response. My engine performs better with the OE intake than when I had an aftermarket intake fitted on a stage 2+map. Sometimes more BHP is not the best, as it is how responsive the engine is. The intake moves the power higher up the rev range so you have to rev it more to get the best. I found the intake on the car actually dulled the driving experience, as it felt flat at the bottom end and not very quick. I take the approach that MINES do with their cars. Not going for big BHP but going for a car that is responsive.

There are no adaptions to really take place, when fitting a induction kit. Blocks 032 will show the trims and I am sure they will be well with in 10%+/-
The issues with induction kit is its allowing the turbo to spool faster on part load/throttle (part throttle speeds up air flow via the turbo) driving and the ecu is adding the correct fuel to meet the lambda value of 1 for light load driving. You wont find the car over fueling or running rich.
Just long term driving at part load the MAF is seeing more air per cycle and more fuel is needed. nothing much can be done in the mapping as the map at part load will already be at lambda 1.
The fuel maps only change at.
1, when runing evevated egts under full load over x amount of load. (at the extream these maps run LEANER close to .81 vs the .71 stock
2, 90% load request over 3000rpm the lambda will come down to .89 for the torque band and .83 from 4500rpm for the power band.
So part load driving 0% upto 89% load request the ecu is set to lambda 1 upto 4000rpm then 4000rpm to 6520rpm .95 to .90.
The only way around it is go for a 1:1 ratio linear throttle map trying to reduce part throttle load request, We have done this with a few Focus STs and gained around 50miles extra per tank. :wink:

Couldnt agree more Nick, lol!!
