If you were talking about overtaking me on the straight, that's because I was trying my hardest not to let my engine lean out
Really need to fix that...
Edit:
I wonder if that could have been the cause of the lower power figure on the last tune...
Assuming that a single dyno pull in 4th gear doesn't completely suck all the pressure out of the system but only drops it slowly towards the end... So the upper part of my rev range could have been running at say 80% of the fuel pressure it should be running at. If it was consistant, then that would have been included/accounted for in the tune right?
Pulling hard through 2nd / 3rd / 4th was leaning it to the point of misfire / detonation, so not a great feeling on the straight.
I THINK that the Walbro 255 is affected more by a lower voltage source than a stock pump or the bosch 040 that was in there beforehand... So if I wire up a direct feed to it with a relay coming off the ECU wire, it should pump more...
But will it also have a 100% speed whine all of the time instead of varying at Idle speeds? aka, stupidly loud?
