that didn't happen with me.... but perplexed why there is a 'return" at the filter and not at the fuel rail. In my case, when I loose pressure when the car/pump is off - that trapped air has to be then pushed out through the injectors??

So adaptation values are how much FUEL is added at idle and then
the multiplier during acceleration??

my multi in bank 2 almost at 8% exceeds the limit? Well then why doesn't the DME just beef up the additive and tone down the multi??

my adaptation values:
Bank 1 Additive .06 ms
Bank 2 Additive .04ms
Bank 1 Multiplicative 4.8%
Bank 2 Multiplicative 7.9%
