If these turbos make 420-440 consistently and hold over 400 whp to 7k rpm on pump no meth, maybe 445-455+ on meth? that would be worth it to me. Also these turbos would better in better effiency in the higher boost range. Anything over 400whp on stock turbos is at the max of the stock turbo and out of effiency.
