Rough running and stalling when pressing throttle

[Rawze]

The only program help that I have on record from your e-mail addr is from several years ago.

Rough running and stumbling, cutting out can be a lot of things.

(blind guessing)...
== Maybe Air getting in the fuel?.
== Maybe the cans were not gutted properly and it has a lot of back-pressure in the exhaust?. - Has anyone tried to run it around the block with exhaust piping disconnected before the first can?, or behind trubo?.

== What is the engine ser#?

Maybe some more details, like when it started acting up, etc?.

== Has anyone taken it on a test drive and collected data on it with a proper screen file in CT?. - That is the next step, as CT will tell you whats causing it to act up, cut out, stall, etc..

road test screen files.
