I got a Celtic Tune remap K&N air filter this transformed the car,they said 200bhp and it feels like it to.MPG around 55,its in gear acceleration that is the biggest improvement,I think it was around £250 all in.Not bad for nearly 25% increase in powerDon't mean to revive an old thread but I found it an interesting read, mainly because I am looking to get my 2.0 HDi remapped.
Couple of questions, firstly the air filter if you put a K&N or a piper cross on the HDi it can effect BHP? I always though air filters didn't really add or take away much in the way of any BHP for an image and mainly made it sound nicer.
Next, what kind of BHP could I expect from a remap + a DPF pass-though/delete? and will that be safe for a stock clutch?
Would be happy if I could get to the 200 BHP mark with some nice torque... safely lol!
???I don't think that they actually remove it, I assume that they are switching off the reporting function via the ECU as they say it is "delete". Whilst a dodgy practice, I would think that technically it is legal although an insurance company make take a dim view of it, if you don't tell them that you had it done as part of the re-map. I assume that you have told the insurance company that the vehicle has had the re-map, as your are obliged to do under your policy T&C's.
