Finally got to pulling a log... the 6466 feels extremely laggy compared to my PS2 and I know the lag can be helped by fuel and the tune. But honestly, I love it so far, it at 17psi on 92 octane feels like my PS2 with meth at 24 psi (just not in the lower rpms haha) what I have noticed as well is no limp mode whatsoever since I have installed this turbo.
Couple things of note I have noticed is even though the spring color combination I installed in my wastegate is supposed to be 11 pounds but when I do a map 1 log (wastegate spring pressure for the JB4) it shows about 7.8 pounds. but when I go to map 2 it holds 17 so I guess it's all good. I might put one more small spring in when I get a chance though to try to get the wastegate to do 10-12 pounds on spring pressure.
Overall, pretty happy. Just need to figure out a couple things with my meth injection and I will be shooting for mid 20's.
here is a log I took recently I just have nowhere to actually pin out 3rd so it is not the best.

Oh and huge shout out to Jeff@speedtech the install took me awhile, but everything fit exactly how it needed to without any modifications! although I did state I installed my PS2 without removing or even lowering my sub frame I don't think that would be possible to do with the speedtech kit and if it was it would be a total nightmare! Pictures to come this weekend!
