Hello, all. Getting parts ready to switch to an external wastegate, and I have a spare set of headers with a pipe welded just under the turbo flange, waiting to be ceramic coated. Just needing some opinions on how much wastegate I'll need to control boost in the mid to upper 20's, perhaps around 30 if I start chasing a number at the track. I know Precision, Tial, Turbosmart all make good units, but I don't have any experience with what size is needed to control my setup. Also, I have not decided how to control boost yet, but I'm leaning toward Boostleash. Open to suggestions there as well. Thanks in advance, all.
