Spec is Fully Rebuilt YB with T34 with cut back blades
MSD Stage 3 chip using Bosch 803, 3 bar, coil-pack conversion, closed loop

Its always been a very laggy setup with full boost not achived to high up onto 4000+ rpm (the exhaust might have something to do with that, Straight threw 3" with only a tiny scorpion backbox)

Engine has only cover 1000 miles since rebuild once some more miles on her i will visit MSD and go for siemens injectors and another chip and get him to check it over
