| S4R Cat removal
Hello from a newby!
I took delivery of my new pride and joy S4R two weeks ago.
Already done 1500 miles and in process of fitting the usual bling.
Just done removal of Cat and fitting of Spareshack straight thro pipes.
Can anyone advise how this may effect engine mapping?
Am I risking running lean and hot, or am I just worrying to much!
Any advice would be greatly appreciated! |
