Wow, just got off work and this thread really took off. To where, I don't know, but took off. LOL! But I appreciate everyone's input and Orange thank you for your concern about my car. I guess the only thing I can do is hook my gauges up once they all arrive and see where they are at. Bruce also did suggest that I take it to another dyno just to double check on the boost number also. But nonetheless, the car is tune and soon, I'll give it a test on the track once I get all the essentials in the car, the gauges, tranny cooler, and of course the slicks.
Mach1 and all others interested, heres the file on the final run today.

Oh yeah while I'm at it I haven't heard our resident/president experts explain how the car made 429ft lbs of tq a day earlier and 389ft lbs today on the same dyno? Please don't say the weather. :lol:

DON'T go wail on your car!!!
No offence to ANYONE here, but either it's taking too long to transition from closed loop to open loop once it goes WOT(wide open throttle) or the settings are wrong for it to go open loop.
14:1 at 10 psi is not a safe tune
Psssssss...........locked VS unlocked converter.:hello:

Another important factor is that JBA usually measures air/fuel ratios via a tailpipe sniffer. This method has proven to be an excellent way of measuring the ratio, but it is not perfect at low rpm. At low rpm, an engine may not be producing enough gas to displace all of the atmospheric air in the tailpipe, and this will produce a false lean reading because of the extra oxygen - as one can see in the above chart.
Danny you going to Irvine event? I will bring my laptop and we can take some readings...
I thought the tailpipe was the shitty way of measure? Best would be before the cats have any say so on the matter.

When Bruce tunes a car they weld in a bung before the cat so that AFR would have been pre-cat.
I used to work there so I know this for sure.

Ok.....lets just be fair here. Nobody really knows why the 2 boost readings are different. Let's just leave it at that. I finished my tune today and the cars drive real well and it feels good. Bruce just wanted to be safe and don't hurt my car and I appreciate that so the tune is on the conservative side. But he finished the tune and here's the numbers.
