after my start problems my 496 bbc (454 stroker)are now running and driving smooth and really nice, but i am on 38 % + on global fuel and 26 % + on idle and 10 % + transient, spark are unchanged and works fine

chip are 3554 , my question are should i have a larger chip ? reason i ask are that i would like to try the E85 fuel that needs about 30 % fuel raise compared to ordinary gas, (we got true 99 octane pump gas) , i dont think my present chip can deliver that much fuel , my system are 3550

E85 are amost half price due to taxes, so it is worth a try

You could install an adjustable fuel pressure regulator and have all the range you need.
