Hi,

I have a UK turbo currently running 241 bhp with a H&S rear box and a Green filter...... (112k miles but new short engine at 40K by Subaru due to pistonslap, has full service history)

I've since added a H&S decat centre but I was looking to get a H&S decat down pipe fitted ASAP but wondered if this would result in the car needing a remap as I'm worried about it running lean?

Advice please....

Thanks BB

 

i have a MY99 Uk Turbo with a full decat and it ran fine (engine out at mo for other work), general opinion is that they will be ok like this but you do get better results with a remap if you have a mappable ecu of course
