I've had a remapped VW Golf 2.0 TDi 140 and I was happy with the 160+ results.
My new car is a Kia Ceed 1.6 CRDi and at 126ps it's a little short in the power department. Can any one recommend either:-
1) ECU re-mapping company that can deal with Kia's
2) Diesel tuning box supplier
I understand that remapping would produce better results, so that is my primary choice. However, with the car being new and under a 7 year warranty, I'm also considering a tuning box that can be removed for services. Main reasons are that I've seen it suggested that during a service, the dealer may either be able to see that it's been re-mapped (voiding any future warranty work) or zap it if they work on the cars ECU. MY previous VW Golf never had an issue during services though.
It's a lower powered vehicle but if it can receive a power increase that would be the icing on the cake.
