running 0.8mm jet. with no restrictor. i think its too much flow. even tho richard lashed the ecu for a smaller flow. roger suggested like a 0.5mm jet.

i will check if its running less boost.
update*** just went out with the 0.5mm restrictor. no flow on the bar graph. turned the SC on the guage and still no flow. i will now check the next size restrictor. 0.7mm.

I am not knowledgeable with Minis but all Minis I have encountered uses 100% methanol. The next logical step is try running 100% methanol. Perhaps a smaller jet with 50:50.

Just to recap, what is the fuel injector size?
i think the fuel injector size is around 400cc/min


***update***
thanks to all who have helped above. i will try those suggestions now. and hopefully we can get to the bottom of this.

@Howerton Engineering
did you have similar experiences to what i noticed when you tune the minis r56?
