Default Question about Cobb Pro-Tune - installing Helix Catted D/P this Saturday.

Anyone have any ideas on the numbers I will be running after the pro-tune?

I am currently Stage 1, with the only mod being a catback Tsudo N1 style exhaust, which I understand adds nothing.

This weekend I am going to TDC tuning in Concord, NH, and having my Helix D/P (catted) installed along with Crucial Racing (vendor on NASIOC) copper gaskets installed, along with a Cobb heat shield.

Instead of just flashing to Stage 2 93 octane off the shelf Cobb map, I am going to have TDC dyno tune the car & create a custom map for me.

Any idea on what WHP I will be running after that? I understand that a stock STi is usually 240-255 stock WHP.... stage 1 must have kicked that up a little bit....

I will be getting a before/after dyno plot, so it should be interesting - I am looking forward to it - is Stage 1 and Stage 2 really a different beast? (hopefully the custom tuned Stage 2 will be better than the off the shelf Cobb map for 93 octane).
