Also, depending on where you live… I’m in California with gas that kinda sucks, so I usually go a bit heavier on the e-mix to prevent any timing issues.. so for my e40 tune, I’ll use the calculator and target like e45.

oh okay thanks and yea i know gen1 b58 stock fuel pump can handle aslong as there is a tune to support it but i just didnt know if i can go from a e mix after a race night back to regular pump tune or something cos i only go racing on the weekends soi just didnt see me running e30 all week after being reasonable if that makes sense

I personally run the stage 2 91 octane map and fill up on 93 with a gallon or two of E85. Car seems to love that setup. Running catless, that config smells a little better than straight 93. I'm in NY and our 93 is shit. I logged running the stage 2 93 map on straight 93 vs. my current setup and timings are just so much better.
