It's not really the real duty cycle... I often get 114% or more. I wouldn't worry about it.

Like I said, I think I've hit 98 or so, but the IDC isn't as easy as looking at a percent. It's a formula that depends on what RPMs you're at when it happens. If you can, log your RPMs, IDC, and TPS (throttle Postition Sensor) in an Excel doc and send em to me. Do a full run if you'd like, or a single gear.

Also a list of your engine mods if ya could. You should be able to go stg 2 without having to mess with injectors.

I have a silencer remove, K&N drop in, TurboXS TBE and I use tactrix to log, but no EM yet... I mean, no tuning or anything yet.
