I mean that powerdyne's fuel upgrades are not sufficient. The FMU is a vacuum operated mechanical diaphram that pinches of the return line forcing in more fuel under boost. The inline pump increases fuel pressure. These upgrades have to be cut into your stock steel lines.........not very attractive. This setup will allow you to get by but your stock injectors are running over 100% duty cycle. The alternative is larger injectors with tuning, a tuner shop will have to do this, It can be expensive but tuning with ls1 edit on a pc with the car on a dyno, along with a wide band o2 sensor for accurate air/fuel ratio tuning is better than a rinky dink hypertech programmer. A hand held programmer will not get the job done. The supercharger is for 98-02 camaro/firebird. It has 500 miles on it, my buddy used it and I bought it but I have not installed it. Tuning is 500 bucks give or take, look in your local area. Gauges can run up to 200 to 300 total, but it all depends on whichones you get, if you install them, ect. The electric fuel pressure is by far the most expensive, at around 175 or so on ebay. Youll spend a little on rerouting the upper radiator hose, extra vaccum line, maybe clamps, parts house stuff. And a wrecker ride from the install point to the tuning shop.
