Yeah, between the exhaust and the LICP I installed, I also noticed a decrease in spool. The car just seems to respond so much better to the throttle, and it's quite easy to get into boost if you're not paying attention...
I had the alignment done earlier this week and the tech even commented on the fact that the car just seemed so eager to run when we took it out for a quick road test after he had finished.
My Buschur filter kit arrived today also, so I'm thinking about throwing that and the Walboro in this weekend. I'm curious to see how much, if any, the cone filter improves on the throttle response and spool time.
Let us know how the car feels once you get all the parts on and load in the flash.
