Only reason to even list five would be to cover different HP goals or budget. No particular order, because I’m recommending each based on a reason.
-If you’re flat broke, but have unlimited time & some DIY know how the EBay direct replacement seems to be the best budget option.
-If you’ve got unlimited budget & plan to make 600+whp DBV2 FMIC & replacement crash bar.
-If your goal is 500-550whp my larger option, Baun Performance V2 FMIC. This covers the Hybrid turbos & full frame turbos with MPI & LPFP upgrades.
-Last, but definitely not least would be the two that cover the needs of anyone who’s neither flat broke nor going for broke & planning to make more 450+whp (aka these two cover everyone stock up to 450whp, because that’s the practical ceiling for performance on both of these units).
Baun Performance V1 FMIC or Do88 Direct Replacement.
