regular, mid-grade or premium gas. what do you use on your LT1???
I have used premium gas for my LT1 ever since I installed my HPIII. This is because there is a setting on there that tells your LT1 that your ONLY going to feed it 93 octane gas. Well, I went back to stock programming and am thinking of going down to regular gas. What do you guys use???

I've never tried it, but theres a chance that your gas milage will go down slightly negateing the change you saved going with the lower grade. Purely speculation. The money for rebuilding your bottom end can also come out of the moeny you saved.
It says right in the owners manual to use premium. All those people driving around using premuim with their 9:1 compression ratio are wasting their money, but you actually need it buddy!
This guy didn't have very good luck dropping it down from premium.

it seems that if you put 87 or 89 in an lt1 or any high compression engine, it will tend to burn more rapidly because of the lower octane
i think i tried this with my camaro (usually use 89) and went wit 87 because i was almost broke, and it did seem to go down a lot faster, and i was doing normal driving (but, it is pure speculation on my part as well)
thanks ice for bringin this up, i'm thinking of gettin a 4th gen z, and this was a question i was going to bring up
