Hi

I have a MY01 with a Prodrive kit installed.
I am going to be doing a full exhaust upgrade and thanks to some research will now be doing Ecutek as well. Now I am a little confused as I thought a PPP was simply an upgrade to the ECU (like a piggyback perhaps) but on another site one of the guys talks about swapping out the whole ECU for a Prodrive one with pics of 2 different ECU modules

Can you shed some light on this for me?
Can you still Ecutek a Prodrive ECU if it is completly different?
Any additional advice would be greatly appreciated

Thanks

Stretch
