A JP4 lump on vts management seems to run leaner at WOT, I put a 3.5bar FPR in to try make it a bit better. The GF quite often sees 45mpg average from her engine, it is in an AX though.

Yeah I'm getting 45 mpg at a constant 70 mph from mine at the moment. But I want MORE!!!! I've had 55 mpg out of mine before, that's the highest. But I know it can do better. Guess I'm going to have to get a mappable ecu at some point then.

i was just wondering can rs turbo injectors be used on the saxo turbo?? the beige injectors are good for around 220bhp from memory

cheers

ax is around 15-20%lighter than a saxo.
jp4 is higher comp ,dif cam spec.maybe sensors are not same postions ,head is dif shape ,spark plugs are different --lots of variables
