has anyone ran the tuned version with sidewinder worlds blend? i have a friend with that combo and we can't seem to get it tuned in. i run a mr ninja and it tunes wonderful, but his just will not tune in to sidewinder. it wants to run 200* and makes "o.k." power. we both run rc8's so i guess it could be a fuel tank issue. this is his third tuned grp and he's on his 4th or 5th fuel tank. just trying to rule out the fuel.
