    I mixed in 100 octane with 91 octane both times (407 & 440 whp) to make 94 octane. So the only difference was the cats and the placement of them, the fuel mixture was the same.

    I got my car dyno'd again, and I gotta say I'm very surprised with my results. The only difference from the last run to this one was 200 cats (metal) welded at the back of OEM sect 1 instead of 400...

    This kit is rated at 7 psi of boost.
    The reason I had a nice smooth line this time is because I added some 100 octane to my 91 to make approx 94 octance. I wanted to make sure timing wouldn't be...
