Gamma + spacer = FUN
Had a chance today to test drive my car with the combination of the dual Gamma exhaust and the 5/16ths spacer: Power in the mid and upper ranges is definitely enhanced; pulls like a freight train to redline, and sounds awesome doing it. My first WOT run I was getting a peculiar juddering/hesitation on punching the throttle in 1st, on shifting into 2nd, and a bit on shifting to 3rd. Thought it was perhaps related to the spacer install, and hoped it might improve when I get my Osiris reflash this week, but then had a flash of inspiration, turned off the VDC, and tried again. Bingo...smooth pull right through the gears. It is cold here today, which definitely reduces traction, but I've never had the VDC cut in on dry pavement before, and I have done WOT runs in similar conditions. One more bit of evidence demonstrating the gains with this combo.
Can't wait to finish things off with the Osiris reflash this coming week (and probably 1 or 2 etunes after). Looking forward to seeing the final result on the street, and hopefully on the track next w/e.

Made this video last week for chefz
Car is a 2008, not 07 like I put in the beginning. Car made 4whp up top from the cat back alone and I believe 7whp through the midrange. Then while the car was on the dyno they installed the Injen intakes and made 270whp on a mustang dyno. Car is a freak! Mine made 262hp with the shockwave, hfc, injens, and a tune. The cars baseline was 254 I believe, and the car is auto.

aren't there people on here making over 300whp with just bolt-ons and a dynotune or is it just the type of dyno?

oh wait, sorry man...i just read your post here. probably the type of dyno, elevation, and temperature has a lot to do with it.

There are some here:http://www.sfzcc.com/forum/showthread.php?t=8857
Yeah the dyno was the same mustang dyno for my numbers and the white one above. It could be temperature or could be a problem with my car. Who knows, every car is different. I will dyno it again soon to see where I am at. It's funny, when I had just a catback and intakes, the car was running very rich, around 10.2 if I remember correctly. Then once I installed the HFC's my a/f went to around 13.5 so that did not leave much room to play with the tune. So maybe my computer was not used to the cats or what. I guess we shall see.
