Ya I don't know what the guys were thinking that printed my two dyno sheets, both should have been displayed/printed differently.
I just began trying to improve my tip in. Thanks for reviewing everything and pointing out the erratic cells in my map, I had surprisingly not noticed them being like that.
Since I was and still am tuning my car, I kept the timing conservative to be on the safe side while tuning afr. I got on the dyno this day just to see where I am with HP and because it was a dyno day, I will be tuning more, turning up the boost a little later and advance the timing a little more as long as the knock stays low, and I will end up upgrading the fuel system for some more boost. thanks

Looks like the tires broke loose as it hit about 22 psi at 5600 rpm, 25000 PIM boost, 11.5 afr, logged 7 degrees adv leading timing, knock 5, looking at a log of a 3rd gear pull today. I just turned up the boost last night and did a little tuning, 22-24 psi, so now it's breaking loose the tires much easier in 3rd gear. Same tires, 265x35x18 bfg g-force kdw.

Ya I know, I was supposed to get one email today for the single turbo dyno files, just sent them another message on fb, that place isn't too far away so I could drive there if I need to, I will get it back on their dyno soon again anyway. and still waiting for the the email from the other place where I ran it with the stock turbos, that place is like an hour away so I been trying many times to get them to email it.

yeah your peak torque area is 5200-6600 rpm which is pretty common for a big single. The output readings were:
Uncorrected: 442.17 whp 363.35 wtq
SAE (calculated 1.05 factor): 463.94 whp 381.24 wtq
STD (calculated 1.07 factor): 471.41 whp 387.38 wtq
conditions were
78.77F/25.68C ambient temp
28.77 in HG/.974bar ambient pressure
66% humidity
It's always interesting to see how things vary with the weather.

Tom,
Did you try doing some pulls in 3rd gear and comparing the mixture to pulls in 4th gear. i started street tuning 20 psi last week. In third gear I am noticing an 11.0 (still rich with pre turbo WI) mixture right now but in 4th at the same boost it dropped to 10.4 but I ran out of road at 6500rpm.. Wondering if you have seen the same.

Yes it is not unusual to see slightly richer mixtures in a higher gear. I think it can be because it will hold a klittle more boost in 4th gear and it can use part of the values from the row below the row that you are tuning, so if that row below is set with much higher numbers then it will run richer, you know what I mean? So try taking a real small amount out of that row below, assuming you are datalogging with datalogit. IT also could be if your air temp table makes the fuel too rich at higher air temps, because your air temps can rise a lot more in 4th gear compared to the lower gears. .6 change in afr is a lot, shouldn't be that much.

Yes I am running the same style cold air intake I made for both setups, see my thread on that.

I don't think the water gets superheated, I think the purpose of injecting it pre turbo is to get better atomization, and it does something to the efficiency of the turbo if running high boost. The water soaks up some of the heat out of the air as it's compressed supposedly. And you're not supposed to inject water after the turbo if it's also before the IC, it should be either post IC or preturbo.

I shredded the 3rd gear in my tranny, check out the pic. I was doing some tuning, lots of 3rd gear pulls, right when I hit about 19 psi as the boost was still rising in 3rd gear it sounded like the transmission exploded lol. It was about time anyway, this tranny has been making a whining noise in 1st-3rd gear for a long time now, high miles, lots of drag racing on it, I have been wanting to replace it anyway.
