I finally got round to a remap on my mkV GTI. I opted for the Morego250 conversion - that's a remap plus a Miltek exhaust. The car is transformed. The power comes in very smoothly and there's still minimal lag from the turbo. The biggest difference is higher in the rev range, where the car now pulls very hard, right to the red line, where the standard GTI runs out of steam. It's now considerably faster than the standard car, yet completely manageable. The chassis copes just fine. The miltek sounds and looks great too. I came accross a mate of mine in his scooby sti a few days ago and he saw me and floored it... I kept up very easily. If it had been wet, then he would have pulled away, as 250bhp in the GTI does envoke the traction a fair bit in the wet - buy ou just adapt your driving style to the conditions and all is OK. I did check with my mate that he was giving it plenty - he was. So, worth getting 50bhp on your GTI? You bet it is! Now I have a golf that is quicker than a mkV R32 (in the dry) and way better looking! If you are any doubt about what a remap will do to your car, don't be! It's made a great car, well, even greater!
