can i use the apr chip with the bcs boost controller or would it be a waste of money and to just go with the apr chip?

and whats a good turbo timer to use for the A4 1.8t

 

i would say its waste to have the boost controller b/c the chip will have the boost raised. BUt if u already have a boost controller teh chip may help alittle b.c it changes mor ethan just the boost but that would be ur call. A dealer may also be able to help u decide.
