The engine has about 5 tanks on it so far. How much more fuel do you think it needs before i can put a slightly rich race tune on it?

Thanks

Novarossi factory pre run?

Idle 1 tank or 10 min of fuel with the fuel you will be using , after that tune about 75% performance for a few (3-4) tanks on the track then race tune . Ive seen people (pro drivers who are friends) do too much break in after nova pre run and lost compression almost instantly ,ooops , ive explained to them this method and why ,now they are going through wayyy less engines
