Factory or aftermarket turbo?

Assuming the OSP is a quality set up??? For $3,500, wouldn’t you gain more performance at a lower price? Was dead set on factory turbo, but with only a 6 month warranty, and a 925cc vs 1000cc motor I am somewhat undecided. If the Boondockers and K&T turbos are far superior ($5,700 plus) and the OSP, Silbers and such are just cheap low end kits, the cost or savings probably wouldn’t make sense. What are your thoughts? (Assuming you already have a 1000)
