No, I don't think the Noble is too slow

However stuh (in the gearchange thread) mentioned a power upgrade for 2.5 litre cars from the factory. If it's a factory job rather than a shady superchip then I'd be interested - I'm sure Warren @ Mole Valley mentioned a factory power upgrade to put the 2.5 ahead of the GTO3s...

Anyone here got the remap, and is it effective / reliable??

There has got to be some extra refinement to be done on the software - mine still takes ages to start when hot as it's pumping too much fuel in. It's so rich on warm start that you can smell the petrol wafting around the car.

Hey perhaps it's just me - the GTO3 demonstrator MV had also wouldn't start when warm when I was sitting in it (same issue, too rich, petrolly smell)

Joust - I thought you'd upgraded from the 2.5 to the GTO3... if not, and you're speaking to the factory tomorrow - let me know on this thread or by mail about the upgrade, cheeers!

Well the guys at MV sales reckon they can't tell the difference between the 2.5 and the GTO3 performance-wise

More power's always nice, esp. when you've got an Ultima behind you on a track day, but I'll always be after the latest ECU map. The software must get refined over time...

As an aside, does anyone here ever get above 21 mpg?? Is mine running too rich or am I simply a nutter??? (the 21 mpg was a 200 mile drive to Somerset, never letting the boost gauge EVER get above 0 psi) That was seriously a test of my self control.....
