+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.
Odd, i get ~320 miles to a tank of gas with my PE850's and 30R. I cruise to vegas from orange county which is ~260 miles, and im still at ~ 1/4 tank when i arrive. Also i've never had a problem with cold starts or idle with my PE850's, in fact they idle great! IMO tuning has everything to do with these two issues..
