Have an 02 800 setup to run on premium-wash is very hard to read usually. Found that running it on 110 oct produces a very pronounced easy to read wash pattern. So if the motor was jetted according to the wash while on 110 octane how much would u have to increase jet size when switching to 91 pump fuel? Would it be 2-3 or more??

I normally start with three, but be careful because engine timing factors in too. Start extra rich and test slowly and don't forget to do some tests under heavy load (hills or powder) before you go full on with the sled.
