I have the customers 548 on the dyno, ordered this to try to gain tstat hsg clearance , the air horns already hitting the only dyno tstat housing I could get to fit at all. Gonna run it with it and without it of course and see what it does to the hp.

That may be the ticket there to get the clearance for the volute
