What ever the case, it's clear A/F is the reason. Eriks and TopTiers cars both have my headers on them which is a completely different to your car. So 13s may be a good number for a 350 with a stock exahust system, but with a header it may like to be rich.. as can be concluded from the two dynos.
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.

Daniel thanks for paying for this dyno. You really do stand behind your products.

Alright, my dealer is coming through for us. He has an appointment for a dyno tomorrow morning. The car he is bringing is a stock 350 with 24,000 miles on it. He will be doing the dyno on the very same dyno I used. So we will have confirmation on my dyno results. Once Combfilter finishes his results, testing should be complete.

OK so yeah me and my buddy Chad will be doing the install. I am going to have to bribe him with some alcohol and food.
I will be dyno'ing next tues on a dynocom dyno (pre header install). I'll post that baseline here. Then get with carchitect and his reader around his schedule. Then install the headers, go back and dyno and get with carchitect again.
ha remember that dyno fund money? can i get that back
? joking.

So... I havent seen the dyno results. The dyno was performed three days ago, but no one has seen the results yet. From what I have heard they are not very conclusive. There was a "issue" with the dyno. What ever that means?
Combfilter, you are the one who could possibley give us the most detailed info on the headers. Would you like a dyno fund?

I will post the after dyno image as soon as I get them, from talking with the dyno man, Todd, he said peak HP gains where around 6/7 hp but tq wise it was over 25 wtq which came on much sooner and was there for much longer than stock.
The dyno broke while they where dynoing another car rigth after the stock 350.

I don't see how the Lexus scan tool could be any more helpfull to diagnose this issue than an OBDII scan tool. My cheapo OBDII scan tool has totally adequate resolution if you are logging just one or two parameters at a time. It's not like you have to datalog EVERYTHING simultaneously.

It will tell you when/if the car is pulling timing or not. That way you know if it's a header design problem or the ecu is adjusting for the change. Other than that, yes the a/f will be pretty much the same as a dyno.
BTW our cove at joe pool looked like glass today. We will be out next weekend. Dust is officially going to be off the wakeboard.

I try to only post when I have an opinion that hasn't already been expressed by someone else or to back up a shared opinion that is under attack. All other posts seem like a waste of everyone's time.
You're missing my point about the OBDII scan tool. It can provide high resolution datalogs of each primary O2 sensor (AFR), long and short term fuel trims, timing advance, coolant temp, and throttle plate position all across the RPM range. What else would be needed?
Regarding the lake, we went out on Saturday, but didn't find any glassy water. I'm surprised you've waited so long to get wet. We've been rocking the Air Chair for a month.
