wastegate

2 questions: 1. Is there any reason to go with an aftermarket BOV other than the fact that it sounds cool? 2. Should I go with a stiffer wastegate spring? What all does that entail? Can you just go with stiffer spring, have to reflash, or more? Is it worth it? Thanks,

When Precision released their new 46mm Wastegate, we were asked by our clients to do a side by side comparison with the Tial 44mm, you are probably wondering, why not against the Tial 46mm?? and the reason is because even though Tial makes a 46mm, it is the 44mm that has the same mounting flange...
