Hi @toot,
It wasn't ecotune, I went to the guy I know for the last 5 years, he is based in Glasgow, MartinAutoClinic, ha has done previously couple of diesel cars I owned and I was happy with his work.
The petrol I use is e5 Shell V-Power but air filter and spark plugs were not changed, the car has only done 14k miles.
Warranty is great to have but will it cover chipped engine and DSG? I doubt that. The car is on extended Skoda warranty for another 1.5 year, even though it is on 69 plate.
Air filter I will change in a couple of thousand miles during my next service, I will do it even if Skoda says it does not need to be done until 40k miles for example.
The car initial test had shown to have 152bhp and 241.3Nm torque, after remap we achieved 172bhp and 323Nm, I wanted to go with save numbers so not too overload a gearbox. I also did a DSG remap.
After 40 minutes of driving home I honestly did not see much difference, for example with diesel engines I noticed the difference straight away, with petrol not so much, it does look like the car picks up better from 50-60mph but during normal driving I can't really tell the difference, weird. May be something to do with the engine being petrol or I just don't want to floor it! lol
Even picking up kids from school the car behaved as usual, may be gearbox need time to adjust? May be I need to change air filter and plugs? Will give it a few more days and have guts to properly floor it.
I also not sure if my fuel consumption will be affected, with diesel engines the fuel actually got better but with petrol who knows, will see.
I remember that my automatic diesel BMW after remaping stopped changing gears from 3rd to 2nd on some hills as it had enough added torque to pull the car through, with Karoq, the same roads and the same driving experience as it was before remapping.
I trust the guy, he has very modern dyno road and he spent 3.5 hours playing with the car so do not think he just took my money and did nothing.
