    Wow, great deal - considering buying and not installing until I can afford the clutch, after 32k miles most of which on Vit Stg1 and your TSP stg 1 clutch is starting to slip...

    Ugh, decisions decisions...

    Pretty cool. The stock turbo is really showing it's tapped out up top... but the midrange is impressive. Hope you sell a pile of them.

    My old lady's still content w/stage 1 (and if anyone w/an Si hasn't tried it yet... whadderyouwaitinfer!?). If she says she's getting used to it/bored, I'll throw more money your way.

    What ethanol percentage was the dyno tested car at and is there any concern for the Si's engine internal strength at these power levels? Thanks!

    I believe they mentioned 35% and to use 30-40%. Wonder if there is any benefit staying at 40 vs 30 though?

    37% is technically 100% advance/boost adder in the tables.
