That combined with probably not reading his plugs either is why this happens.
You can't make a blanket statement and say 23-25* timing is what every 100-150 shot combo wants.
He needs to pull the plugs out of his motor read them after each pass, and know what the AFR was, along with the timing, F&N jets, Fuel Pressure, Nitrous Pressure etc. etc.
After the plugs have been verified to be clean and on the money, then you can say it needs 23-25* timing.
Hell we don't even know what kind of plugs he is using, he could be spraying some TR5's or TR6's and if that is the case 23-25* is WAY to much and shouldn't even be sprayed. (this is just for example)
Like you said every combo is different.
