So shot out to Jason aka Megahurtz and any other tuners on this site for their skills. If any of you are lucky to get his assistance with your builds you are in good hands.
Here's what Ai said:
Your tuner is giving you solid, "engine builder" advice. In the world of high-boost, stock-internal LT1s, running slightly rich is essentially cheap insurance.
While leaning it out to a crisp .82 or .84 might pick up a few horsepower and make the car feel "snappier," staying at .79–.80 provides a massive cooling benefit. That extra fuel acts as a heat sink, keeping the piston crowns and the top rings cooler—which is exactly what prevents the ring gaps from closing and cracking a land.
Why "Rich and Retarded" is the Pro Move:
• The Safety Margin: If your methanol pump has a momentary hiccup or the ambient temp jumps 20 degrees, that "slightly rich" mixture gives you a buffer.
• Longevity: You are making 750 rwhp on parts designed for 455. The fact that it’s lived this long and feels great proves the conservative approach is working.
• Drivability: At .79–.80 Lambda, the car will be very "forgiving" on the street.
The Final "Streamline" Plan:
1. Keep the
drop: It protects the pistons at peak load.
2. Keep the .79–.80 Lambda: It protects the rings from heat.
3. Enjoy the car: You’ve achieved the "Holy Grail" of LT1 builds—750 rwhp with a fuel system that isn't stressed and a tune that isn't "on the edge."
Since you've got the hardware and the safety margins dialed in, the only thing left to do is keep an eye on those Nitto 555R2s.
Give it a shot if you want to see what it says about your builds. Just feed your information into google and when you get the feedback click on show more then scroll down and click on Dive Deeper in AI Mode. After that you can type anything you want feedback on after you get the results.
Just something cool I thought I'd share.

LOL this thread made me laugh. Thanks for the kind words from you and everyone else. I still lurk here and have been tuning a ton of LTx stuff, just for my partner shop so I'm behind the scenes. I'm also tuning the BMW S58 platform, which is quite complex. It's kept me busy and its usually easier to work with the shops vs the car owners. Except for the people I've met on this forum. I've had the luck of working with some of you and you all know your cars inside and out and its easy to work with you all.
There are a lot of good LT tuners out there and some not so great ones. I've been fortunate enough to have so much positive feedback from my work because I treat people the way I would want to be treated if I was forking over my hard earned money for a tune(which has gotten quite expensive these days).
I have a whole 3 pages I could write on AI but I'll spare you all the lecture. And I'm someone who is in the tech industry and architects, deploys and manages Public/Private Cloud Infrastructure for large scale business need. I use AI every day. I'm flattered AI says I'm correct....which I know I am lol. But lets all remember, AI is only as good as its trained to be. It can get you in the ballpark but ALWAYS rely on your tuner please lol. Now if anyone ever builds a publicly accessible AI model that is trained specifically on tuning cars.....al us tuners are out of business lol.
