i could be alone on this but i have 2 gallons on my btts and the top end still sucks. so slow. my bottom is crisp, tons of power, and idles great all day.. but the top makes me wanna stick a .38 in my mouth.. it never gets into the upper rpms.. when i lean it out it goes to 300+ deg and still isnt singing like the other btts's.. but im sure it could bake cookies like no other tho... can anyone help me?

im using the stock shimming .08 mm, c6gtc plug, 6.5 restrictor
