The other night I had the new alternator test and it was tested good. Then last night I tested fuel pressure with another gauge that I had laying around. This one has the gauge and a 45 degree elbow on it so it came right off the rail. This gauge read 42 line off and 36 line on. The hood mounted gauge has a bit of line to travel to it but read 46 line off and 38 line on. I didn't have a third one to test which I would of liked. After running a compression test which the numbers were all in range of each other, I upped the FP based off the lower reading gauge. I moved FP to 48 off and 42 on. Made a couple test hits and the injectors were 78%DC and pump was 375lph. So I was relieved. I was only at 86% TPS throttle but I did notice since I have a VOLT BOOSTER on it the battery volts stayed at 13.6 on both hits but the times I went to the drag strip battery logged at 15.5 volts. I ran out of time to actually run the car at 100% TPS to see what the VOLT BOOSTER would do to the battery volts. I will try unplugging it also.
