I took a ride in Craigs car Monday night and it is completely different than before. He scared me almost as much as the first ride, "before the crappy tune".

Yes, the car felt like it needed a bit of a victory lap and burnout, so We gave one he77 of a donut in a local parking lot, Sam, you still need to get a pic up of the donut.

403.9 whp, the a/f's were fine!
We had some issues with the a/f monitor on the dyno, wouldn't work with my exhaust. A/f's are a solid 10.7-10.9 under WOT.
Ok, I think, I figured this out, the quality isn't awesome because of youtube, but here is my run. I promise to do better the next, especially since I have finally figured this whole posting videos thing out.

Sharif will chime in later, but the design of the rsr exhaust that I have wouldn't allow his a/f monitor to get a good reading. We tuned off the wideband a/f that I have in the car.

I never said he didn't. Nor did I say he doesn't know how to tune. When you use the tail pipe your car runs richer and it's not as accurate. This wasn't directed at sharif.

What I was going to say, is that on most cars with extra 02 bugs, we insert our sensor directly into the exhuast stream.
However, when that is not feasible, we use the sniffer. We never tune strictly on the dyno. The dyno sniffer wideband is within .3 AF points of actual conditions. Once dyno tuned, its back on the road to fine-tuning.
This is the only way we tune cars...never strictly on the dyno.
But the poster is absolutely correct. A direct sample is also more accurate than a tailpipe reading. Overall, we've found the DD sensors, and their wideband module to be the most accurate tail-pipe reading to date.
