U7135, 9r17, 2006 300C 5.7, all stock, no cai, no exhaust, running 93 octaion tune, with only tyre size changed, all other settings stock.
When coasting up to a junction or stop light, from say 40mph the car takes for ever to slow down, it feels like the crusise control is on, which it isn't.
I don't think it would stop on its own for miles on a flat road without the brakes.
I thought it might be the shift firmness, but I put it back to stock setting and no difference.
Loaded the stock tune and it was fine.
Any ideas, or is this a feature of the Preadator tunes? I don't really like it like this. It will stop and idle perfectly in drive when you brake.

Its the tune. Check your RPMs at idle. If they are to high it will cause this problem. I have a 2006 300c and have noticed that there is very little roll resitance even with the stock tune. I think its normal and more pronounced with the tune.
