Since fitting the smaller pulley I've had an issue with the injectors running at over 100% duty cycle at 6,500rpm and above. This is clearly not good!
Swapped out the fuel filter and the fuel pressure regulator and while there was an improvement it was still not great.
Fitted a 190lph Walbro along with a rewire running it straight from the battery via a relay triggered from the original loom and we have a result. Pressures at the rail back to what they should, no pressure creep with the stronger pump and on the RR it was considerably richer all the way through the revs. Nick tweaked the map and now I have good AFRs right up to the limiter and a fair bit of head room in the injector duty cycles. I can now use full revs for long periods without being terrified it's going to lean out blow itself to pieces.
We also swapped out all the lower wishbone bolts at the fron tot try and cure my clonk on heavy load right-handers. I've had the alignment set and so far no clonk although it's a bit slippy out at the moment to really throw the car around. Time will tell. A big thanks to Nick @ Skuzzle Motorsport for all his hard work as usual and also to the Wheel Alignment Centre in Southampton for setting the Geo, the car feels better than ever now.
