I'm really pleased with this car, I've got 2000 miles on it now and it's getting looser all the time.
what mileage do I need to do to fully loosen it up ?
Has anyone fitted the SSTT to a 135i and does it add a risk to the turbo's or anything else as I have heard of some turbos being broken with tunes on this engine ?
I have also heard that the SSTT isn't an easy fit on the 135i as the cable is at the bottom and the splash sheild needs removing, is this correct ?
Does a replacement Air filter help this engine like a K&N and if so, which filter is the best and won't cause any problems with MAF sensors etc ?
I find the tickover is a little lumpy, is this normal ?
Sorry for all the questions and I hope you are all as please with your 135i as I am with mine.
