[QUOTE="LTZ MACH, post: 6270873, member: 26984"] Ok, this weekend I took the pumps that were in my car and replaced them with 2 Walbro 255 hp (GSS342) pumps. I turned my BAP down to 5%. When I started the car back up, the lowest I could set the base pressure was about 67 psi. I took the car out for a drive and the fuel pressure remained high. As soon as I started to get into the throttle, I noticed the fuel pressure dropping and at one point it fell all the way to 35 psi and I was barely in to boost. Now what??? What should I do? Anyone have seen this and know what the solution should be? I have an idea of something that might work but will hold it in to keep from swaying some of the opinion in this thread. Yes, the car is return-style and NOT returnless as they come from the factory. Here is my other thread that this was discussed in previously.
