Thanks for the feedback guys. Alas, I have the P7 so unless I swap to a P8 then I'm stuck with the same map for both cylinders. If the bleed screws can make a fair difference to running then I'll add checking out the TPS and air bleed settings to the list. Given the excellent reputation of Nelly (and how close he is) it would be the sensible thing to do as you suggest Andy. However, one of the satisfactions I get is trying to do as much as possible myself even if sometimes its a very steep curve! Keith |
