So I took off my XZT box which does pressure when I got a Smarty Jr because the literature with the JR says not to stack it. I have been told this is because the JR can't adjust it's timing. Well I have the Revo software so I can adjust the timing to stock levels. So now I'm thinking that I might get a little added power from the pressure the XZT brings to the game.

Does anyone know if the JR does anything to RP? Can anyone shed some light on my thoughts?

 

You can have the XZT programmed for pressure and boost fooling only then use ti.
I just decided to remove my XZT as I keep having intermittant problems that seem to stop when I disconnect it.

 

I run the XZT that I had changed to pressure only with Jr and love it.

 

How did you get it changed to pressure only? I guess you had to send it back? How much did they charge for the change?

BTW, thanks for the replies..

 

Wiskey, if the problems you had were a rail pressure code.... I had those too, I sent the xzt and harness back, they fixed up the harness and I used di-electric grease on the connections then zip ties all the wires so they wouldn't move around. I had no further issues after that.

 

I had two codes. One low voltage at the fuel pump and the other was an invalid skim key this last time.
I may send it back and have them check it.
I've run it with and w/o and notice little differance though.

 

I sent it back to Quadzilla a long time ago and don't remember what it cost me exactly... I think he may have done it for free. Great customer service for Quad and his people.

 

Thanks guys.
