I've got this 1982 fb with a Mariah Motorsport Wide body. I swapped in a 13b Monsterport with a Weber 48 to a 51 IDA Downdraft Carb. I'm trading for an aftermarket 3" o.d. replacing my Racing Beat for an aftermarket so I can brap, brap, brap all the way home? It's a 6 port converted into a 4 port from a 1990 non turbo. Right now, the car isn't Dyno and I'm losing about 60 Horsepower. I have a very bad bogging problem that's not allowing me to have the full power of this monsterport? I have somewhat of 10,000 miles on there and the life expectency is about 50,000 miles before water leaks into the engine because of the port size? I tryed several places of possible tuning, but no of these places around the Bay Area have the right Rotary testing stuff? My options are either Racing Beat or Mazdatrix I Guess. Can someone contact me with information on how I can Tune my car with the Hook up Please.
