I noticed that my car idles a little differently with stage 1 - it seems like it has about a 100 rpm lower idle speed, but it's only a subtle difference. Sure does rev quicker from 3,000 rpm to redline in 1st gear :>

Saki - glad to hear you like stage 1 too. I think those of us with automatics notice an even bigger improvement in overall drivability than you do with the 5-speed. You've not made much mention of your adding stage 1 on these threads. Keep us posted as you and your car are one of the highlights around here.
