Used 1/3 of a tin of proboost tonight in £20 worth of o.max , getting major activity on Knocklink would it be ok to put in NF without using proboost treated fuel first?

 

I would recommend using NF Race over Proboost (I used to be a fan of this though was converted over to NF).

You may well have picked up a bad tank of fuel from the garage so on the first treatment I would personally put the full 330 ml in, this will raise the ron content by about 6; certainly getting rid of or eliminating any pre det or det

(If it doesn't get an engine diagnostic done quickly & drive off boost)

After the first treatment of NF then follow the recommended dosage of 50ml per tank. Again I personally use 100 ml per tank, though I do need to treat the engine well...
