i've spoken with r-tech a few times about tweaking the stage 1 remap that was done prior to the sports cat being fitted, they said it would be fine as it is and that they would only look at the remap if i wanted to go to stage 2 but i don't... the other solution suggested by bcs (exhaust company) was to fit a lambda boss extension which i've had done this weekend. this would take the sensor out of the picture and stop the eml coming on... my only worry is that this sensor must be there for a reason, so by making it redundant is that going to cause any problems?!
also as a side note, r-tech said they won't even entertain doing a remap with a gfb dv+ fitted, again something which i had done after the remap.
