Well the dyno didn’t quite go according to plan, the car didn’t blow up or anything stupid thankfully but it had a really bad spark break up.
the blue line is the 2.6 6466 and the red is the 2.8 6870
At least i got to drive the car home which is the first time since Xmas 2020. Luckily a friend was nice enough to lend me his coils for me to test and it fixed the problem
It turns out the old type prp stalks are well known for being an issue so I replaced all the stalks with the new type and the new bracket to suit and that should be job done ✅
