A quick update.
Gt2554 is feeling great, [MENTION=3805]Tune+[/MENTION] Tune is really consistent and I am really happy how the car drives now. Car is still a tad laggy in certain situations but I went to a track day today at the Streets of Willow and the the turbp felt great! I'm really happy that I went with this turbo. All though I have been to this track quite a few other times this was the first with this car and I was taking it relatively easy to learn the car, especially the rear end with the Pierce motorsports torsion bar.
Here is a little clip of the beginning of the day chasing down an 08 M3.
