Port and Polish my turbo
 

If i have my turbo ported and polished, is it a necessity to have a re-map or could i get away without one, as i am sure it is not going to make a great deal of difference..

You could change the way the turbo holds and comes on to boost... meaning the boost control would be the one needing tweaking the most.

I'm not sure, but I know your meant to re map after header porting so I recon you probably would!

Cheers guys... :D
