I'm new here also, but here's what I got.
There are two chips worth buying: Midnight tuning and Turner Motorsport. Both similarly priced, I have heard they make a pretty noticeable difference but that isn't saying a Whole lot for a stock m42. But definitely a good easy mod.
Midnight will retune if you decide to take it any further, but there's only so much *I* believe they can do without Having the actual car to dyno and test.
I don't know if that helps? I just ordered the Ostridge ecu and bought a tune from midnight so I can change it myself at some point.
