So about how much hp can you get out of this turbo. Ive seen toms kits and they looked great but I can aford five large ones . I just want around 230- 250 horses. If I get this do most dyno shops put the parts on or are they just there to tune and dyno cars etc. And would I need a boost controller and turbo timer or anything like that . Basically what Im saying is what would I need to go with the kit.
