If it were me I'd find a good tuner and have them log the car and look at the output. If you have the tools to log it yourself then you could do that and post it up for one of the smarter guys to look at.

 

With it being only in one gear, and the car pulling like it should and having the drivability that it does outside of this incident leads me away from this being an injector issue. Could still be a fuel related issue though. Getting a tuner and some of the EvoM faithful to give the log a once-over should hopefully shed some light on what's going on.

 

After you hear boom and keep driving....do you get a cel for misfire?

 

no codes!! I've got a new exhaust coming, so it'll go in for investigation when that comes. Looking like overboost in 4th/5th though..........
