Nice gains on the car.
Not to bust your chops but instead of $3,400 why not go this route:
ASP Pulleys (3) ~ $970 shipped
SL55 y-splitter - 10 minutes of work + $80
SI ECU - $1,000 (from memory)
Total: $2,050
Install of pulley's ~ $200
Take the savings and put it towards a set of cams.
Also the comment about wanting a stiffer suspension or larger stiffer roll bars only apply to handling, not straight line acceleration. The stiffer suspension will inhibit weight transfer to the rear.
