I'm not trying to be argumentative, but I still don't think this is the right conclusion without knowing anything about TopTier's timing curve. The fact that TopTier's stock AFRs appeared leaner than Erik's modified AFRs seem like a good indication that there was something weird going on with the dyno or car due to altitude. Also, I've personally tuned my IS350 to AFRs in the mid 13's with good results.

All dynos do read different thats for sure, but I have yet to see a 350 hit 280 wtq on any dyno, on a dyno dynamics at that, but the bottom line is a stock 350 needs to be dynoed on the same dyno.

maybe toptiers gains would be just as good if he got tuned with an SAFC
Daniel, have you contacted the shop that I used to discuss results? Or have you e-mailed my dealer about dynoing his 350? You have his e-mail from my earlier one to you.

The post is #565
Here are some new interesting dyno results from erikbaker. Erik asked me to post these dyno sheets from his IS350 with my header.
279 whp and over 280 wtq! on a dyno dynamics dyno which is known to spit out the lowest numbers.
Here is the biggest thing that one needs to pay attention to on this dyno, look at the A/F ratio, it's almost at 11 at redline. Compare that to the other dyno which never broke 13s.
Now I know all dynos read very different, so I am working with Erik in finding a stock 350 that can dyno on the same dyno so we can see the real gains.

I thought the dyno was going to be done using car_lost's exhaust. See post 531.

All these numbers seem kinda low. I was able to produce 246wtq with the X-pipe and SAFC alone. I also made 280whp without the hedder. Of course mine was on a mustang dyno.
I think the main number to look at on mine is the wtq. Thats a pretty impressive gain. So impressive that I want to do another dyno on a different dyno just to prove that number.
