Yeah after I have installed all performance parts I will get a ECU remap from Pedro but that will be at the very end. Can he do a custom tune for exactly what performance parts I have even if they are not his brand?
Like Fabspeed race exhaust and underdrive pulley

I'm sure he can. Also, FVD/Brombach can create a custom file based on mods as well.

From what I understand the IPD plenum gives a lump of torque much earlier in the powerband due to its shape... I think 83mm is overkill for your typical boxster, with the 75mm throttle being just right.

As for the original poster, with a 3.2 you'd probably be better off installing a 996 intake manifold to go along with the cayman S airbox, since thats where the power is really restricted. There was a thread on Rennlist where a 996 owner installed a 3.2 in place of his blown 3.4 and didnt see a huge decrease in power...mostly because he used the 996 intake and exhaust.
