I have just seen this post from old.
As a new member i dont want to say to much.
but i have seen a z32 300zx.
in the uk with this system fitted and it worked brilliant with No Lag.......
and made 80% more power when done with out any fueling mods.
His dyno was 348.9 BHP @ 6300rpm
non boosted power was 192.7 bhp @6500rpm.
