One of the few issues I had with my i30 was the occasional lag power-wise. With this in mind I looked around for a chip or remap. I ended up with Chipexpress. My reason being that the car only has 7,900 miles on it and I wanted to diable or remove the device prior to its service.
Now the Chipexpress isn’t cheap (£400) but it comes with a 3 year guarantee, is easy to install and remove and comes with a 14 day refund if not satisfied.
I ordered it on the Friday and it arrived the following morning. It took 10 minutes to fit and I left the settings at optimal.
Since fitting I have done 2 journeys, one around town and today on a 35 mile commute. I didn’t expect miracles but expected to see improvement with the lag.
With my foot down there was a noticeable improvement. On short journeys, I had to change gear less and the engine ran smoother. On the commute this morning I really noticed the difference. There is a distinct lack of lag and gear changes are fewer. If, for example, you changed to second for a corner, I can now do that in third.
All in all I am impressed with it and can recommend it.
