..........I have a 2001 cummins with upgraded tranny, 4 in exhaust and an Edge EZ........i can get an older VanAiken box part # CPC ISB 215.235...........i know they both add timing, but will both together add too much timing, and how do u know how much is too much and can i check timing with a scanner....the EZ uses the map sensor connection and the VA plugs in at the vp.....thanks......kim....

 

Too much is bad.

 

You can't stack pressure boxes together, you can only stack a box with a programmer.

 

..........Thanks guys.................kim...

 

No such thing as a "pressure' box for an '01, Larry

 

Correct thanks for the help What I meant was you can only stack a box with a programmer, you can't stack two boxes together
