Mixing pulley upgrade and tunes. Can you buy one shops pulley and use a different tun

[mrb5_supra_wrx]

So bare with me I'm new to b8 chassis supercharged v6 but not new to audi's. But I've been trying to research into it but it seems as tho there's quite a bit of pulley upgrades for our cars now. But is it acceptable to mix different pulleys and tunes? I.e. Apr or forge pulley with a giac tune, awe pulley with an Apr , etc. Is there really any error to it seeing a few people have done it but I can't find definite info on if its legit or not. Thought about trying to make some stuff work being some pulleys are smaller and cheaper like the cts turbo pulley being the smallest but also the cheapest . Wana know if I could use said pulley with like a giac or Apr or EPL etc tune and what are the possible outcomes

Both GIAC and APR will not release their Stage II files without their own Pulley and it's serial number. CTS Pulley is good for like an EPL tune or Chipwerke Pro Stage II. Will they work, yes, but again, unless you obtain the serial number code from someone who's never used it, you won't be able to use just any pulley with GIAC and APR.

All the pullies will work with all tunes. The main issue is like said above, the serial numbers.

yes, it's locked into proprietary tune files. You could get a forge pulley file from GIAC, but the pump file is apparently less aggressive at 17-18* of timing versus the normal AWE pulley 22-23*.
