No melted fans or anything here; the GReddy kit includes wrap for all exposed wiring anyways. The kit is comprehensive, which is why I picked it.
While the Ptuning has the easiest thermal management out of the box, the lack of response is what swayed me away from it. I don't mind doing a bit extra up front to do things right.
The G25 is almost a bolt-on for the T518Z kit. Rumor has it I may be swapping it on for more power, although the G25 will need a BOV.
I seem to be the only person, literally, successfully tracking a turbo FA20, at anything other than a very casual pace. Pays off to use quality parts and planning ahead.

If I'm not mistaken, going without a BOV is what is likely to cause "compressor surge", since there's no relief between on/off throttle? Does the Greddy kit come with a BOV and you decided just to not use it?
I liked that you said you experience full boost around 2300rpm which seems like it may just be as good as it gets. From what I've seen w/ the V2 Ptuning kit, it seems it does boost fairly quickly as well. Perhaps it's maybe a few hundred rpm behind the Greddy kit (dyno graph below). It seems the curve is linear as well w/o any major spikes.
One last major thing I cannot seem to understand: the ptuning kit with their EL header seems to make amazing numbers at only 6psi (around almost 300whp, I believe). It seems the Greddy kit needs 10psi to hit high 200's or so - correct?
Now is this because of the type of turbo the kits are using? If that's the case, so with you switching to G25, would you be not only possibly spooling even faster but doing better in terms of efficiency (i.e. more power w/ a 6psi spring than before?)
Thanks again for all your contribution with everything on the forum. I hope you make a new thread to share your results if/when you switch to the new turbo.
