Single T76 LT1 Just Back from the Dyno-
Just some info I stumbled across... the TC76 actually makes a little less power than a standard T76:

So Dave, get a T76GTS in there already!!!!!! J/K

Hehehe... To tell the truth, I've got just enough to get just about all of it to the ground. I hear people all around me tell me they're so proud their street cars have these stupendous HP figures and how the tires go up in smoke if they just barely press the gas pedal. I just stand there looking perplexed. Why is that great? I want the car to go Mach III pronto, not nearly stand still and annihilate my expensive tires

I have the 14psi Turbosmart spring in it but it's opening up early. I need to get a boost controller. The chassis dyno (dynapack) said it briefly touched 12 psi then, after it opened, only was pushing 11psi up to max RPM of 6200. My boost gauge (Autometer) may be calibrated different but it only shows 10 psi when the waste gate opens up. I need to get a boost controller on it and lock it at 14. The motor is built to take 800hp but I don't have the fuel system for that. Besides, like I said, I can barely get the power I have to the ground 
I'm still running the mail order tune, also. There's plenty more power there. I just don't need it yet.

So far, I will stay with the MAF. I'm really pretty satisfied with the AFR numbers I'm seeing during cruise and WOT even though it's running in Open Loop full time. I ditched the stock narrow band O2's because their placement didn't seem to give accurate readings. I've been tempted to go to Speed Density with a designated 2 BAR MAP sensor but I've read several accounts where users of that method have a consistent and elusive problem with a "tip in" stumble. I'm getting closer to deciding to go to a tuner system like FAST or something similar so I can tune on the fly.

I did really research the MSII and had the DIYAuto.com labeled cable, Assembled(by them) MS and the MSII chip. But there's an absolutely infuriating lack of info on installing it to an LT1. I don't know if these guys that have it are lazy, don't know themselves, protectionist(don't want other guys doing it), spiteful ("Hey, Nobody f*cking helped me. Go f*ck yourself") or most benignly, don't have the time to respond. I've PM'd people here, on www.ls1tech.com and the MS forums. I get either NOTHING or some insipid response like "I use it and like it". I'd even offered to pay people, via PayPal $100 to just give me the info on;
a. How they attached the Reluctor to the HB.
b. Where they got their sensor.
c. How did they attach it the Sensor.
d. A baseline tune.
etc.
I'm pretty sure that if I purchased the 36/1 reluctor wheel and the ford sensor to read it, I'd have my signal though there is a guy that has found how to read the Stock Opti but, somewhat understandably, he's not giving that info out. He's selling it for over $1,xxx.xx and it includes the MSII incorporated into a modified Stock PCM housing. That might actually be the way to go when you consider the cost of the reluctor, sensor, machine work, MSII hardware, wiring and ease of installation. With his setup, you don't even need the MS cable, all wiring has been tapped into the stock harness internally in the PCM housing. He even provides a website for setting up the baseline, with actual screen shots/Menu-Option paths and values to load into them. Then he shows screen shots of Megatune so you can get familiar with it.
