There are tuners in Europe who get 500hp without methanol, I don't think you'd need to complicate yourself with that. As long as there is quality petrol in your area. Here in Romania you can find 100 RON pumps pretty easily. Don't know about Lithuania tho.

BMS makes some nice kits and unique tanks with internal pump mount options.

my mgflasher tune is still in development now…
at the moment my best run was 7.8 sek. 100-200kph
and 3,6 sec. 0-100 kph. we just did a few Maps, yet.

my best run with finished mhd stage 2 was 7,3-7,4 100-200
in the next days, we try to bring the numbers on same Level
… but i had much more work on that map. so it Looks good
and realistic to keep up with that numbers.

Why did you decide to switch to mgflasher?

because of the torque limitations in the g20 series dme's.
mgf found a way to fix that issue with a custom code. mhd still write down the information in the dme, but it didnt worked well with my tune. i ran often in limitations.

now i can adjust the torque limits on my own up to 1000nm
just check mgf homepage.

mgflasher map is not final. mhd was final.
we only did a few map optimizations with mgf.
more will follow.

with mhd i was able to do one or two runs without issues. after that
i was not able to drive smoothly. now i can do run after run with mgf,
no problems.

Do you have any WOT logs at hand? I wonder how did they manage to bypass TQ limits.
