2.5" spacer with front passage blocked to send all air through 1 of 2 passages giving the air more velosity/ energy to act apon the turbine.

I also had the 300k mi+ injectors tested and pop presher adjusted . All but #5 were down to 209 bar(3031psi) pop pressure #5 was 220bar(3190psi) now 4 are 258 and 2 at 256 (3741and 3712psi respectively) I put the 2 lower in cylinders and 4 because theas are the leanest cylinders and the minimal extra fuel/timing they will get form lower pop pressure will help to balance the crank loading. This has retarded the timing ~ 5°(1°/ 10bar pop pressure change) so to day I'll adjust the timing. The advice on line is to bump the timing 1/8"(3-5° )
