Hi

Anyone had their N52 330i remapped as of late ?

Opinions ?

Hi sorry for the late reply as I have only just joined.

I'd had my 57 plate 330i Msport N52 manual saloon for a couple of years and was very happy with it but was getting a bit bored (I usually swap cars every couple of years) and wanted a change. Ideally I wanted a 2013 onwards 335i but these are still are still quite pricey, minimum price I found was around £15-16,000 so started searching performance upgrades for this model and didn't find anything that informative other than a lot of speculation so I decided to get somethings done and see what happened.

I started with an AFE stage 2 cold air intake which cost about £450 and a BMW performance exhaust back box, quite pricey at £750. AFE claimed a 15 BHP gain which I doubted to be true but there was a slight gain more like 5 BHP I would guess. I wasn't expecting any gain from the exhaust, which is what I found, but it did make the engine sound much better and got rid of the annoying valve rattle.

I then had the engine remapped by my local BMW specialist garage (not main dealer), I don't know what software they used but the difference is very noticeable and well worth the £200 they charged. It's hard to tell how much BHP it has gained, but the car is much more fun to drive now, more torque, more BHP and definitely quite a bit quicker.

I also had new Michelin Pilot 3 Sport all around, cost about £620, to replace the terrible stock Bridgestone Potenzas which makes the car drive like a bone shaker and offer awful grip in the wet. They are so much better it feels like I'm driving a different and much better car.

In total I spent just under £2000, a lot less than if I had upgraded to the 2013 335i, and I'm delighted with the results. I will definitely be keeping the car for another couple years now as it feels totally upgraded.
