sputtering and fuel cut at 3500 rpms

[montego6500]

so my mods are in my sign, i am running e85 and tryin to tune safr. why at 3500 does it like fc and the also sputter. no boost leaks and only like 8-10 lbs of boost. up until its does that my afrs are at 11.2-11.8 then they spike to like 13.0. and even adding 40% fuel still does it what am i doing wrong here


thanks dan

Just a guess its a 34, but check them.(Above link) Also use your friends compressors and some end caps, block off the turbo inlet and blow into the 3000 pipe.(Or your equialent) This way theres less risk of spinning your turbo dry.
