A normal TD04 spool is decent, i was getting 1 Bar @ 3400rpm. Took a bit of messing about with an AVCR to get there. Also some fairly short IC pipes and heatwrapped exhaust mani right down to the backbox, dont know if the heatwrap did anything because i fitted it all at the same time lol. Thats why i can never understand when people say TD04s are laggy haha, set em up right and they are really responsive. What kinda figures do you get from the hybrid Azz ?
