+1 on poor fuel economy, with any bigger injectors realy.
+1 , i expected better tq #s on an STi (cam timing), but the 07 maps are difficult and the tuner there is tops so i dont know.
+1, 850 injectors are not very good on cold start up and idle poor, especially PE's! DW's are much better for those issues. My car idles to wrong for me. Im changing things up asap.
i love my gt 30r kit on a DD 06 STI. Im tuned to 21.5 psi with meth and 418/403, high reading dyno. Boost almost comes on to quick and she just stops 'pulling' at 55k rpm..sortof...ha. Great powerban.
