The board after mapping

[freddyecu]

Hi all, I have a 147 mjt 120 mapped and defappata with the egr closed of 2008, I ask you ? better also empty the catalyst under the turbine, or ? better to leave... C'? who says serves as a back pressure to the turbine who says, the better to empty it... Attend? your advice.... Thank you in advance

if you want a board you have to bucarlo,as I do with 3 holes with the tip diameter of 12.........never had any problems!!

[msport (exil77grande)]

everyone has their own method, I prefer to always leave the catalyst intact and remove the entire contents without break of the dpf.

I meant the catalyst where is the probe labda no dpf

according to you, freddy...the exhaust gas,after the map will be many more, and probably also a p? the hotter and therefore more "voluminous",as soon as they come out from the crowd and better if you are or not something that "stands in the way"??ragionaci you, and draw your own conclusions from that....
I can only bring an es...if a door is made to pass 2 normal people at a time, do you want to go 4 overweight all together..what do you think would happen??

I and may I add if you empty the pree catalyst which ? also matallico and makes you suffer to empty it, you'll have a larger diameter and a pressure drop at that point, I like to always leave the constant diameter both with regards to the dpf, I put a tube specially made with the same diameter of the exhaust is the same for both, with regard to the pree there are special drowunpipe if you write that it is not expedient to empty it, even if on a 147 we have emptied and it doesn't change anything

ops... if you speak of the catalyst to leave it original!!

[neo]

leave it original and also in my opinion and then not, and said that after a rimapatura smoke; hence must increase ecesivamente
