Ok. Here is my feedback so far. TURBO SPOOL is much faster. This thing pulls a lot quicker, and throttle response is that much more responsive. Maybe the faster pull and spool is making me think the car is faster getting up to boost quicker. Also the sound is just absolutely incredible. Its really intoxicating. I found myself going through the same tunnel 4 times last night just to hear this thing CRACK as I downshifted from second to third and from third to fourth.

It is just a whole other beast.

I have to take this thing to the dyno now and see how it responds. The car is still FLASHED with the stock tune. I will probably reflash it back to TUNED once I make a few pulls to see before/after DP install results.

QUESTION. Does my tune have to account for DOWNPIPES now? Meaninig, would i have to modify my tune to account for Catless DP and optimize performance?

Anyway, this is what a quick log of a THIRD GEAR pull looks like. Can someone chime in? Is the Light blue and Light Pink areas of the graph NORMAL?
