Relax guys this is the loose conversations
I do not know if you have watched the B5244t5 engine since 2005-
has other candles than the 2004 vintage even as the My2005
since 2005 there are significant differences that present negligible identical parts of T5 to R
I had a basket of parts from R 2004 and S60 T5 2004 then 2005, 2006 and there were differences with each year
It is these differences 2005+ they most closely approximate T5 to R. longer Spark plugs, coils (grey plug) for My2006, different cyl. head etc.
I do not rely solely on catalog data, I have been collecting experience for over 10 years and every year the model was different in every Volvo.
I know that on the B5244T5 file we can do the power we want, but tuning is a lot of experiments that are not written on cards and we have to check how it works. I will share my experiences with you in a short time how works Rfile with B5244T5 2005+ engine
