As the title says, with approx 700hp, do you need other mods to support your engine? Or is this safe? Can this be achived with just software and downpipes? Or what is also needed? Prefer just pumpgas without Ethanol etc.

Thanks

Its definitely doable, but you have taken up any safety margin. One hiccup with fuel or timing and it could be disasterous with OEM internals.

It will do it, but like guy above said. One hiccup or mechanical issue and motor is done for. Basically, on borrowed time

To be clear, I meant 700 at the crank, not wheel 😎

For 700 crank you probably only need an unlock and tune with downpipes or maybe even a piggyback. The S58 makes 600 whp pretty easily which is probably around 700 crank.

Does the computer adjust tune for race gas automatically?

Up to a point, after that there is a diminishing return. Running straight 100 octane won't give better results than 94-95 octane on the stock tune.

+1

for better fuel to be worth it, you need a tune and map to take advantage of the extra octane

I mean the M4 CSL does it, but as someone else pointed out, at the m4 csl price point they might take into account the cost for warranty repairs or reduction in life.
