yes.. B&M vortech.. they are all the same.. but they are hard adjustments.. as in if you are CONSTANTLY running rich then it would be a good choice.. if you are fin at some pms but lets say rich at idle and partial throttle you should invest in something more..like a vafc.. you can adjust the fuel + or - 50% per 500 rpms.. and i USED to have a fuel pressure gauge under the hood.. it sucked.. becuase you could not see ti during driving conditions.. but that alone will not help you.. you are haveing a tuning issue.. from what you say.. the pressure gauge alone will not solve the issue.. id invest on an in car fuel pressure gauge.. like the one i have (autometer mechanical pressure gauge and an isolator) and an egt... then you really can tel if you are trully running rich..
