Hi there, i have a tuned vauxhall corsa vxr. Had it mapped a long time ago running a base map with 14psi gate pressure on the garett gtx2867r turbo with tial housing. The map is also setup to run the siemans deka 630cc injectors as well.

The car was on the rolling road this afternoon and made a healthy 260bhp. fueling was bang on at 14psi gate pressure. The only thing the dyno man found was at full boost (14psi) the car was missfiring, and we have replaced the plugs to hotter ones and a new genunine coil pack but its still doing that. Also the car is still giving a fault code with the second lambda sensor even tho the map has it set as decat (car has no cats at all)!

Could someone possibly have a look at the map and see if theres anything in there that could be causing the misfire? Said its a very rich misfire at 14psi.

I have had the map taken using a Kess v2 master version as well.

Many Thanks for your time

Kind regards and happy christmas
