where can i buy one for a 02 ls1 cause every place i have looked all they have are ones for an lt1 i need it for an ls1 anyone know where to get one let me know thanks

 

The fuel system in our cars doesn't allow for an adjustable fpr. Hence the reason you couldn't find one. If you need to add more fuel to compensate for a lean condition, you'll need to do it via the pcm.

 

Ditto on what Dmon said. The only other option is to run a external fuel system.

 

actually, if one was to run with a 1997 corvette return type fuel rail, and change pump out and run a return line, an adjustable regualtor could be placed on the fuel rail. probably more money then buying a tune.
