Do you have a fp sensor at the rail to verify your bigger pump is actually allowing for more pressure to reach the injectors, as well as something to record your AFR's?
I am more than likely going to the SL55 pump. I know Rob is working on a fix for our fuel issues as we speak. I am just not sure what the details are with that. Right now I do not have a fuel press gauge installed, but it wouldn't be a bad idea at this point. Could I just run a gauge off the fuel rail into the cabin?? I do have have a wideband A/F gauge to monitor the A/F ratios. According to Dave (Bulldogger), when he switched from the stock pump to the SL55 pump, they had to scale back the injector duty cycle to 80%. That is huge! You really do not want to come near 100% duty cycle on the injectors as you probably already know.
