Hi all, is it worth decating my 1.9tdi, I've heard different stories about loosing back pressure etc but also heard the turbo spools quicker. Has anyone had it done and is it worth doing thanks
 
If you using the stock turbo it makes no difference to power from what I've seen.
Yes spool will be slightly quicker but the stock turbo is hardly laggy.
If you do take it out make sure you log boost as the N75 map may need tweaking.
Cheers
