Then I guess its time to look for a place that will cut out the secondary cats in the stock exhaust at a reasonable price..

As I mentioned earlier, we're still in use of our secondary cats (using stock catback) with the S2 flash - I wouldn't bring the torch just yet. We'll be upgrading the catback anyway since it's essentially a boat anchor.

DPs/FMIC are the most critical parts of the system.

Question, is this regarding stage2+ or just stage2?

Good news,

I just got off the phone with GIAC and it looks like they have been doing quite a bit of dyno work on the 335i as they are putting the finishing touches and completing testing on the Stage 2 flash.

It appears that the exhaust and secondary cat removal will be recommended but not required for the Stage 2!

Catless downpipes, FMIC and intake are still needed.

Updated the first post:

Captain's Log 01/14/2010

The tune continues to amaze me. It has been rock solid with no problem or codes of any kind. Just perfectly smooth and consistant performance with the same results with every touch of the gas.

The Flash has also made me a better shifter as I can shift "Bog Free" 100% of the time on any gear.

I can hardly wait for Stage 2 to come out. I have been told one more week... I will update this post with Dyno Comparisons with the Piggybacks.

Also, I don't know if the GIAC has a "lean cruise" feature implemented or what but I have noticed an increase in my average MPG. I can get about 38MPG at highway speeds pretty consistantly. Here is a video demonstration:

[u2b]<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/A2fS4Xb8XpU&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/A2fS4Xb8XpU&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>[/u2b]

Stay tuned...More to come...
