Yes, please....
Lets make sure everything is inline with the stock unit first.... then get the 85mm MAF for a z06 or GTO and we can work from there.... i would be more than happy to guide you through adjustments on another Fbody file letting you open a compare file and copy and paste to your own... a wideband would be a must for precise WOT adjustments....

I'll have a scan log posted up by tomorrow afternoon. And then we can see what we need to do for the MAF. I'm going to be going down to Sacramento in a week or two (80ft above sea level) and I will try to hop on a dyno down there. I want to have the MAF, 98mm lid and underdrive on by than to see what improvements have been made.

So I plan on getting a wideband installed here in a few days...maybe this weekend. Whats the best bang for the buck wideband that I can use in conjunction with HPtuners? I had an AEM UEGO in my mustang but can't quite recall if I could log with that specific model. Thanks

Now many people like the gold colour very much and that is the same as that a now more and more people now like hunting for treasures, and unlike before nowadys a many advanced device have been invented to help people with their road of hunting for gold and among varous kind of devices, people like gold metal detectors best, which have really give them a hand and help them in differnent aspects.

WTF is that about ^^^
bwolf:
I use my Aeroforce Scan Guage with a spare signal wire split to tap into my C5Z, Just ran it on a toggle switch.... But its up to you...
Scan Guage is nice since you can see everything thats going on when your laptop isnt hooked up

I have been running an AEM UEGO. I have tried the two of the Innovate ones, both took a poop on me very quickly.
So I may be calling Tea to find out about the light weight LS3 valve. I pulled a dummy move yesterday, shimming the springs, I had the cyl pressurized pushed down on the ex retainer to break it free of the locks and opened the cyl dropping the intake in to the chamber. If I can't get it back in to place with a pen magnet through the guide and another to align it through the intake port, well, the heads will have to come off. Then the other valve will go in, if they are that much lighter.

I got my new GM LS3 hollow stem intake valves today from the dealership (#12569427).
I was only expecting them to the exact same valve but with a hollow stem to make them lighter, but I was wrong. They look much more finished than the stock L92 valves. They are fully machined on the top of the head and on the bottom side as well, where the L92 piece looks cast. So if your looking at complete cylinder heads on ebay or something and are wondering if they have the hollow stem valves or not, check out the bottom of the valve for a possible give a way.
I had to weight them for myself even though I had seen posted weights in other threads. I saw a 19g difference between the two.

Haven't had the truck to Infineon.
I spoke to Brian Tooley at length yesterday. Got the valve back in place but I am gonna pull the motor out anyway. I have the motor ready to pull out of the truck right now, just 2 bolts and lift it out.
Gonna swap the valves to a 2.10" LS3 valve, put the old springs back on it (barely used) and put it back on the dyno just to see what it does. It will have a little more compression due to a head gasket change, will be 13.5-1 now instead of 12.95 (4.125" bore / .054 going to 4.1" bore / .040). Then I will see if it is a push rod issue (5/16 .080 wall). If it clears up I will run it like this for a while. Only worry is the preload change with the thinner gasket. Right now I am .050" on the exhaust and .060" on the intake.
I do however see a cam change in the near future. So if I still have a problem, I will most likely pull this cam, stick a bigger one in it and upgrade the pushrod to a 5/16 .120 wall as I don't think I can get a 3/8 push rod to work. Might be able to fit a 11/16 push rod but not sure.
