I have a modded wrx blob eye with a VF43, 3" decat+uppipe, 550cc injectors, sti intercooler and a few other bits and had it mapped back in jan but the last three months i have noticed the sot on the back of the car worsen and i can smell unburnt and exhaust gases all the time. The car hasn't missed a beat so not quite sure whats the cause

Any thoughts would be greatly received thanks.

 

Who mapped the car.

 

duncan - race dynamix

 

Did he add pops and bangs?

 

Hi Rich - gimme a shout if you want me to pop by when I am in the area and I will check it out for you.

 

Thanks mate i willl take you up on that! Let me know when your this way and have half hour that would be very much appreciated. I took your advice about the lamba sensors and got them checked and they are fine apparently.
