Very pleased to announce that yesterday we found the problem has finally been fixed, and looks like it was the fuel pump.
Car made 430/385 on VPower and 473/425 on a 20% meth mix, which was a great result given the temp in the dyno cell was 22 degrees!
We also found the O2 sensor in the down pipe had failed which would explain some of the rich running, but all in all, a happy result in the end

Saw your brother's turbo'd civic there too Jura

That's very good results there and good to hear you are found fault what this caused as I said,usually those two culprits are fuel pump and lambda/O2 sensor ,in yours case has been both which is not usual,but yes happens

Yes Latso car is there for bit of upgrade
