Well I've spent 3 days on this, I must be doing something wrong. A customer had an Esmeril turbo kit installed with the 1000cc secondary injectors.

As I want to tune the car properly I set the MAP to matrix mode and Injector injection to sequential mode since I want control of the staging points like other ECU's. I can get the car running beautifully everywhere before staging. But when I try to stage, the car just bogs as if I took my foot off the gas pedal.

I have staged it at 2" of vacuum and +2PSi. I have changed the %stg from 0-90% (correcting the map everything), I have tried adding a lot of fuel during staging and barely any, it always feels the same, a sudden loss of power as if fuel or ignition was cut. The wideband does read the fuel both rich and lean depending on what I do but it always feels the same. It only happens at staging point (even if I change it) so its definitely staging related.

Has anyone had a similar issue or have any input? I'm really starting to get frustrated as it seems like its something beyond my control.

So it was going super rich afterall. I was just being cautious and paying too much attention to the wideband. It's all good now
