I am strapping an S258 on my AGP turbo kit components in a couple of weeks. I can let you know the track results in comparison to the .48 50trim when I run it if your interested ben. no other changes so it should be a very accurate comparison because even the mani, 02 pipe and wastgate will be the same parts that you guys gave me.
