Exhaust leaks usually make ltft go way positive

check you intake install for leaks check catch can if you have one. make sure the tiny gasket on the maf sensor is not torn or creased

but if your on petrol with a petrol tune -18% ltft indicates a problem

check you didnt flash an E85 tune by mistake

Yea, I thought so thanks for clarifying steve. I think its best you datalog after you make some adjustments @Lakitu
