pump gas Impulse nytro on Av gas

[evan3000]

I was curious how Paul's pump gas map would run on av gas? I would like to take the boost up just a little bit more. say 20 psi. Is this fuel going to throw much of a wrench into the mapping? It runs really well now. or am I asking for trouble on shimmed only motor?

I have a MCX nitro with shim and run 17-18 and have seen 20 by accident. Willing to bet Paul's mapping is similar to MCX. After 18 #'s @ about 5000ft I feel is pushing rods and head studs. Av gas is a great fuel, my machine has 4200 miles on AV . Can be hard on A/F sensors from what I hear.

depends what impulse kit you have. if you have the extra injectors you should be ok. doesnt hurt to call impulse and ask tho.

What kit has extra injectors?? I thought they just came with the big 750cc injectors??
