Popular opinion seems to say it's laggy, It's not laggy in my car. I think a lot depends on how it is set up, mine makes respectable boost on 1/4 throttle and is very linier in it's onset coming on to full boost at 3000 or just under then maintains it up to 7500. I'm using the FC-Data Logit default tune as I have not yet got it to the tuners.
mods are
HKS adjustable camgear on exhaust retarded 4 degrees.... anyone who has this and hasn't got a big boost in low and midrange torque hasn't done it right...no argument!!
lightweight flywheel...6Kg
3" turbo back exhaust....pretty quiet...probably legal
600x300x75 fmic
modded plenum...front throttlebody R33
Apexi Super Suction pod filter kit cold air box
Sard fuel regulator, VN fuel pump
HKS2540 turbo split dump pipe
Power FC
E-Boost
I expect to have around 210 to 220rwKw when I finally get it tuned but i'm more interested in good power and torque right through the range than big peak power numbers
