I just went from a stckr/475 to a 63/68 t3 gated ed 475.
I picked up some power for sure.
Spinning and only about 60psi on the dyno made 754 I believe.
I was at about 725 with the stckr/475.

I'm planning to order up parts for an external gate to feed the primary. I have a 1 inch spacer between the manifold and 63.
I also may go 480 before too long. Streetable 900 - 1000 is the current plan tuned down to around 700 for the street.

If I go with a spacer mounted gate what would you guys recommend for size?
What spring tensions would be the best for both worlds I don't mind swapping for the track of course.

If I fab a spacer would it be better to favor one side of the divided airflow?
Any problems with tial or turbosmart. Both seem to be good.
