Hi all, i'm new here having just bought a Signum 3.0 cdti. It's truly a lovely car, but next to my alfa 156 2.4 it's shockingly slow, especially when it comes to throttle response. It's only done 50k and it's an auto, so i thought i'd fit a tuning box to a) improve throttle response and b) maybe improve the mpg. I don't want outright power just extra driveability.

i bought a pro-bitz box but this doesn't seem to fit. I know the dtuk ones are a quick fit and don't actually use the rail sensor plug, but one further out and on top of the engine. The probitz was for the pressure sensor, which i found out is buried deep within the engine.

Anyone have any experience of any other brands that are a simple 5 minute fit? If so, would love to hear what they are.

Cheers.
