I have read that you have an M-Engineering tune for this car, is that correct? Do you know if they support E-85 Tunes for this engine combination? After seeing the APR tunes released for the 718 platform it has me curious about the path of E-85 versus Pump 93 Plus octane booster.
Having switchable tunes between E85 and 93 would be fantastic!

E88s are the only answer. Mine were here before the car was.

Questions about the Deman 4.5L:
1) Expanding on post # 72…
[https://rennlist.com/forums/718-gts-4-0-gt4-gt4rs-spyder-25th-anniversary/1286917-another-completed-deman-4-5l-718-impression-review-5.html#post17936460]
What is the approximate peak horsepower figure of the 4.5L engine that is intended to be strictly a 93 Octane engine with very spirited street driving (full throttles and redlining through the canyons) without any intention of ever putting higher octane/race fuel/octane boost in it? (Do we have a peak torque figure for the same scenario?)
2) Is the engine redline the same on the 4.5L as on the stock donor engine? (Please answer for the stock 3.8L 981 engine and the stock 4.0L 982 engine.)

4.5L conversion has unchanged redline from stock: 7800rpm for 981 and 8000 for 718

@JCR-Porsche unsilenced race installed.
Ears bleeding.
Absolutely love it.
Car feels faster, which is an even wilder discovery than the sound.
