what dyno chasis was it on and was it calibrated? that seems like an awful high gain, especially for the 04.

just to clear things up before you guys go on a rant about the a/f ratios on my dyno let me tell you why it looks like im runnin 14.0
the guys at the shop are using a sniffer style wideband 02 and since i do still have a cat installed it doesnt give the most accurate readings and from their experience if the machine shows a 14.0 it is in actuality a 12.9-13.1.
to ease my concerns they hooked up a lm-1 in my second o2 on my header and we made a pull my midrange was staying right around 13.1-13.2 and my top end was dropping off around 12.8

No rant here. That A/F looks great coming from a sniffer wideband. Congrats and keep with the mods. :)

thanks.

the guys at torquefreaks have earned my business due to their commitment to helping their customers. i paid for an hour of dyno time and they worked on my car for about a hour and a half trying to make sure we got the most gains without running lean. i am gonna be working with them to start bringing more parts in for the spec and more mods will be following. i think my next 2 will be the bs removal and also the mid-pipe. and then more tuning.

looks good but I'd still be wary of those a/fs. the cat won't affect it that much lol. you can see the instant jump in hp correlates to that major lean point there. I'd enrich that 2-3% around that spot just for safety.

I just checked you CD site. Looks like you have a great all around vehicle. HP, VRS and now SS make the downpipe for our car. The BSR is a good mod all around. I would do that, a pully and cams. Considering your car is already exceptionally high on a dyno for the mods it has, I can only imagine what numbers you would drop with the car fully bolted.

Those are impressive gains just for having added an S-AFC. Just goes to show how big of a difference good tuning can give you. A number of the turbo'd boys will use an S-AFC on top of their stock or JWT ECU and net similar style gains, so your numbers do make sense. Must be a real fun to drive car. Just imagine what it would do with a strong set of cams in there.
