can i do a diode install if I have the apr chip 93 octane?

 

I dont think there would be a point in doing so.

 

a diode tricks your ecu so you can up the boost... a chip ups the boost anyway... so it wouldnt do anything, since you have just get a mbc and up the boost if thats what your looking to do and dont worry about the diode..

 

Dont need one unless you hit limp from time to time.
