197 PRE-CAT "Y" piece removal....

does paul think he can map it out mate?

£300 plus vat?

rang paul first before i bought the Y pipe to double check he can map it out and he said yeah no problem,you'll never fully get rid of it though but he can massively improve it
 
mapping went well,only made a couple more BHP and the same with the torque figure,mid range is where i've seen all the gains though,roughly 14FtLb of torque at just over 4000RPM,i'll post the graph in the "Y Pipe Gains" thread
