on that basis i'll be selling it again sharpish :)
£350 for 4bhp isnt quite what I was expecting.
I think with a stage 1 map you will not see much gain as the standard filter is still able to flow the air needed for 240bhp.
Also you need to leave whatever filter you have chosen on the car for a week and then do some more logging as the ECU needs to adapt.
I think after that you will see 250bhp.
It will be more responsive and maybe better MPG.
When I had the ITG and exhaust I was MAFing at about 330bhp and now with the Pipercross Panel its 300bhp. So you can see the gains with bigger flow.
Thats a 2+ ED30 BTW.
If you goto Stage 2 or 3 now it will make a difference but give it time to adapt.
