Looks like they refer to it as the XS packageYes. Call when you order though and make sure they give you the variable regulator. They make it both ways.

It doesn't accomplish the same thing. I puts out no more voltage than my stock generator. The difference is that my voltage goes up when it is needed. The pump,injectors,and ignition get something that makes them all work better only when needed. The only way you can accomplish this is to run 16 volts all the time. You don't dare do that. The volt booster is one of those few things that does everything you want it to do when you want it to do it and it costs pennies in comparison. Nothing compares to it. Nothing replaces it. It's something that all of our cars will benefit from.The alternator is not nearly as cost effective, but accomplishes the same thing and is supplying a consistent voltage.

It's a generator. You,and most people,call it something that it is not. Here's why.And it's not a generator, there is a difference.

The demand on the system is much greater than the factory setup which does fine with the factory wiring. Were asking it to do much more. I have extra grounding/dedicated hot wires and run a volt booster. The main effect I'm looking for is high pressure fuel pump output. Most of these pumps drop volume excessively with 14v at pressures over 70. Increasing voltage haswe4Mateo said:Simply not true, it's only NEEDED, when your current system can't keep up to current needs. Good grounds make a bigger difference in injector, ignition, and fuel pump reliability/performance than just voltage. 16volts will make up for mediocre grounds to a certain extent but will not provide more performance than enough volts with great grounds. You only need enough volts to do the job. Are you logging voltage from your stock alternator? It wouldn't matter if you were using a vb, but with a good alt, if the volts stay above 14, you get the same results, only it's there all the time. Doesn't your ignition need good power even when you are not getting on it?
Is your pump hotwired?Agreed. My single deaschwerk was falling off on the big end, threw the volt booster on and all is well.

To kidglok, with a dw pump falling off at the big end...how fast are you going and what alt do you use?
Thanks.
i noticed it on the street when i first got the xfi installed. i was consuming the same amount of fuel that was needed for a 10.7@127, so figure around 580-600hp. its a year old (new)kirban 120 amp. this was at 62psi reported fuel pressure before it fell off.
The different generators for our cars are putting out about the same voltage. In most cases the difference between the available generators is the amperage output. This makes no difference to the output of a fuel pump. The only way to make it put out more volume is to give it more volts.with a dw pump falling off at the big end...how fast are you going and what alt do you use?
