Anybody having to change the cylinder trims when running a full tuned exhaust (ie muzzy)? Obviously the main fuel map has to change but im wondering about the individual cylinder trim. Im getting detonation in what sounds like the rear cylinder @ WOT and ive already bumped the fuel up 20% over a muzzy tune. So either my header is moving way more air than the muzzy one (doubt it) or the cylinders are running vastly different from one another. I have an wideband air fuel gauge but that doesn't tell me individual cylinders. Thanks.
