I'm still not sure which BCS to get. (Please don't tell me to get a chip. I know its better, but I have my reasons)
My question is what is the difference between the two? The Split Sec/ABD only seems to tap into the ECU via wires, while the Greddy install looks different.
Sorry if this is a dumb question, but why are the installs different if they both do the same thing (if that is true)? Is the SplitSec one electronic while the Greddy isn't?
Thanks in advance.

Re: Diffrence between Greddy Prof-Spec B vs Split Sec/ABD (askthefool)

the split sec only raises boost to 1 bar, and the profec b goes up to 43psi.
Since you arent chipped and on stock ecu? You cant go past that 1 bar point anyways(without diode).

Re: (askthefool)

i believe the split second is manual while the profec b is electronic.
greddy profec b i'm sure about, split second i could be wrong.

As far as I know installation of the Greedy Profec B does not require tapping into the ECU wires while the Split Sec does? How can that be explained.
