Guess what my P38 MPG will be!

As I mentioned, it was via the computer. I did a similar journey last year with a similar payload and achieved 25mpg. I've had a PSI Powerbox fitted sincethen and I'm sure it makes an improvement. It sems much smoother at about 2000-2500 rpm as well.

So the real mpg would still be about the 25/26mpg then. The computer does not know that the power box is injecting more fuel so the calculation is out by 2 to 3 mpg. I've done brim to brim checks with and without the power box, on local stuff the mpg is the same in both cases, on the autoroute there is a small improvement in mpg with the power box due I'm sure to the car not changing down on inclines

I'll be honest, I've covered 35,000 miles in 23 months and apart from a few niggles it's great to drive.
