Bud for the cos management what would i be best off with l6 or l8 and would i need a 3 bar mapsensor or would a 2 bar be enough and is the l6 and l8 engine wireing interchangable? Fredy would i not need to modify the exhaust for the cos turbo? Dont think i will ever have more than 20 psi not with the spec i got at the mo.

cheers guys
