Well i finally got it installed and took it for a test drive, i am very suprised of the response. It is just as snappy as the 66, spools just a tad slower but still fast,boost went from 45psi with the 66 to 55psi with the batmo 75 and dropped my egts 300*+. I was scared it was gonna be a lag monster but that is not the case at all. Looks like it may rain tomorrow so next wednesday i will have my stock wheels and tires on and head to the track. Motor is still all stock internally.
