So let's say I go with additives and it turns the inside the engine orange and something does break down and the dealer opens it up and sees the orange residue... Would that be enough to void warranty?

I am guessing a big yes...

You can't run map 7 unless you have race gas.

Figuered.. would 100 octane do the trick? I ordered 15 gallons for 250 and they wanted to charge shipping $150.00 lol.. I am going to pick it up at the race track next week instead.

How are you all running on 93 octane? Mine needs at least 95 and that is the lowest octane you get here... Normally i fill V-Power 100 Octane in my car...

91 Octane

Something has to be wrong here... Does the euro octane means the same quality as US octane?

Wikipedia says:

ROZ 91 = Regular
ROZ 95 = Premium
ROZ 98 = Premium plus

Is this correct?

BMW says i have to fill up at least with ROZ 95.

You can have 100 or 102 octane here at the regular gas stations (Shell, Aral,...)

Ok so i poured in vp103 5 gallon with half a tank of 93 octane. Map 2 on jb4 and I feel no difference in speed but feel a very smooth shifting between gears. It's almost like the car runs heavier. I think I ll switch to map5 for auto running and hope it will help.

This shit is expensive by the way... Meth is a much better option.

Thank you for posting that, I was not big on meth and now for sure I am not going that rout. You know, this modding shit is just enough and I need to be happy with what I have... You can't turn a BMW to a hot rod, just like anything in life too much is not good. I bought a descent car with some potential and now just have to be happy with it unless I add a bigger turbo when available lol. GTR is next or 2014 m3 or m5. I just can't justify paying that much for a car where I can put the money elsewhere :-(

What is the reason behind not feeling the extra octane with my mods? Can't run map 7 on jb4 since its not true race gas... So map2 or map5 to let it auto tune?

you can up the boost manually with a usb to serial cord.. You won't feel a difference because you are still running the same boost as before...
I wouldnt go past 15.5 psi with what you ahve though. You'll feel a huge difference though.
