I have a mk5 gti from 2004 (AXX). I am thinking about getting it remapped with a stage 1 tune. It has done about 306.000 km (190.000 miles). What is your experince with remapping as far as reliability goes?
It has a 3'' downpipe, cold air intake and turboback milltek exhaust so I am guessing it will be pushing 250+ hp. It is a manual so the clutch might slip. What do you think? Go or no go?
