can anyone offer any help please? need some advice on how to modify my file to work better now i have a 2.5"decat str8 thru exhaust fitted.
car is a seat leon 2.0 tdi
pd 140 bkd engine
edc16 ecu

i already have a file that is modified and worked very well on standard downpipe but car now feels down on torque after fitting the larger downpipe and decat. so just wondering what areas i need to modify in order to restore the lost power.
i am literally just learning the ropes and mapping my own car so need some expert help if possible.
i have a partial map pack and am slowly getting to grips with winols but still have a lot to learn so any good advice would be appreciated
thanks
