heavyd:
that fuel pump doesnt look very healthy

this looks more legible

Saint Steve:
Superchips have since Toned down the map and sent me a new map, although im inclined to replace the cam follower and inspect for excessive wear in the fuel pump.

Why did you have a new oem pump installed Heavyd of out curiosity?

The easy fix would be to change the fuel pump, but as superchips and revo say an uprated fuel pump isnt nessasary on stage 2.
My turbo boost/ requested levels are spot on the money, but fueling is the problem.. any other idea's?

heavyd:
I originally had an autotech pump in and stage 3, but was getting some cut, so I sold the autotech. When I put the old pump in the following log on stage 2 showed some fuel cut. Pdt advised me to get a new pump. So got discount at dealers and paid £150 for a new one, which is the logs on the last page. Although I mist say when it went back on the rollers with the new pump it made 5bhp less. I'm no expert but it might be a dodgy pump you have as your logs are similar to mine, might be clogged fuel filter etc who knows. Best off sending pdt your logs and ask his opinion, though he may say the same. Here's my logs on old pump


New pump





 Thats how it should look, mine isnt :ashamed:

Saint Steve:
Would be good if PDT reads this thread. Im hoping the timing being so erractic is caused by the poor fuel pressures.
