Paranoid About My Car
Alright thanks guys for all the input.
- Jim_Patterson: Did you have the gauge hooked up before the nozzle and then routed into the car?
- DragNRacing: So are you saying that a wideband and something like KnockLink would be my best bet and the EGT would just be redundant?
- Warrtalon: I've just been scared to run it hard recently with the I/C piping blowing off and my friend blowing a headgasket, just more cautious than before. I wanted to see if there would be some things I could do to prevent or at least minimize the chance of blowing my engine. But dont worry I was putting that alky kit to good use before.
Looking forward to your responses, thanks again.

KNOCK LINK
It flashes bright red when knock starts - if you are alert plenty of time to lift
I have been in many a car which has blown off the vac hose to the fuel pressure regulator after someone installed a guage or other device T'd into that hose (BAD IDEA) and I have always been able to lift in time by just watching the wide band with the corner of my eye and by using feel

I dont mean to be an a$$, but you shouldnt have installed the alky if youre scared to blow your car up... Get the best monitoring devices i.e. (wideband and knocklink) and have some damn fun with your car... Im sure its fast 
I know you're right, I should have probably thought about it beforehand but the gains were just so compelling for me to get the alky. But now I've become paranoid about it blowing up my car everytime I drive it lol, hopefully it will subside and I can get back to enjoying the car.

The PLX-R500 mounted on your steering column with the LED light set to trigger at a lean AFR would be nice.

Furthermore on our configuration there is AUTO MAP SWITCHING to pump gas map (11.5a/f & 20.5psi) if there is any type of electrical failure to the power supplying the pump. Examples could be, blown fuse, electrical short, loose wiring failed boost trigger switch and on and on.
Our site has referenced these features for two months or so HERE.
The wideband can alert you to a lean condition if there is some type of failure and allow you to let off the gas and possibly prevent damage. You will get an idea of where your tune is at with everything working properly and should be able to notice an AFR fluctation that could show a problem or failure. It would also be best to have a device to monitor knock (knock voltage). By the time your EGT reaches 1650 - 1700 plus degrees some damage most likely could already be done. I personally think with a wide band 02 and knock monitoring device an EGT is a mute point.
However I agree with you on the wideband, I disagree on EGT's. We have run into the 1800*C range with no signs of knock.
Without a wideband, I too would feel "out of control and out of the know". I could not operate a system without all of the monitoring and at the level we do.
Could we? YES. Do we want to? Hell No.
We too use the knocklink, but the knocklink will not save your motor either. It takes input from the user to get off the gas. In our experience the Knocklink comes from LINK set a little oversensitive. I can see it hitting the red, while the OBDII logger tells me timing is climbing as normal with no hold or retard. Normal engine noise will light it up at high RPMs 6800-8500, especially with cams.
We have decided to leave it set up as is, as a warning. If it hits red, then we need to pay attention, but it does not automatically equate to actual knock. Only the ECU can decipher actual knock in it's programming. The knocklink does have a sensitivity adjustment that again, we have decided to leave alone.
We don't want to know when we are knocking, we just want to know when we are reaching the threshold.

Wow alright this makes me feel much better that I can have at least some control or ability to do something if alcohol fails. And I think getting a wideband will just put me more at ease, especially with the prices of the AEM UEGO going down so much, I'll probably get one soon. Thanks for the great, detailed response.

I hear all the time that a WIDEBAND will never give you enough time to let off before engine damage occurs. I do not believe this. If you have a good, fast reacting wideband located in a conspicuous location and are concious enough to know to watch it much of the time while spraying, you CAN let off in time to preserve the engine. You see 12.7-13.5 pop up, you let off, period.
