Running Rich?

[shepsvettes]

I have a wet nitrous setup on my 93 LT1 everything was working fine till I put in a Walbro gss340 fuel pump. Now the car seems to be running rich at upper rpm-s and boggs down a little. My thinking is that with the new fuel pump i either need to go to smaller fuel jetting or get a adjustable fuel pressure regulator. Any thoughts which would be best? Thanks

Since you have a higher output fuel pump. you need a adjustable fuel pressure regulator that way you can control your fuel pressure the way you want. I have a almost brand new Aeromotive fuel pressure regulator for sale (I used it for testing on my car for 2 weeks) it off the car now. It was installed on my 93LT1 vette. It a direct bolt on. I paid $155 from Summit. I will sale it for $105 ship to your door. If you are interested email me BRUCE383@Rochester.rr.com http://forums.corvetteforum.com/zerothread?id=811452
