noel's busy as a mofo so i'll update you guys
it aint making anymore power than 440bhp, dont matter what boost, 18psi, or even 23psi. we think the cats collapsed.
also its now not holding boost, it's spiking. but i believe thats because the exhaust gases rnt escaping quick enough (collapsed cat) and the gases are backing up against the wastegate, forcing it closed and then increasing the boost.
he's also had to change fuel rail (got my tomei rail on there now) because the injectors werent sealing to the rail and had to change boost controller (now running blitz spec s) as it wouldnt allow any adjustment over the 9psi wastegate spring
