Good morning all! Thanks for any info ahead of time. Recently bought a 03 6.0 powerstroke studded with a 5" exhaust turbo back. 4" lift aftermarket Ficm(not sure manufacturer yet) 33" shoes, Sinister coolant filtration system, Sinister fuel filter cap, Egr still in but with upgraded aluminum cooler, new stock OEM injectors x8. My question is on the turbo. With the 5" exhaust, would the turbo be upgraded or still running stock? And how can you tell when it is already installed in truck? I bought it already beefed up except the injectors. Looking forward to learning new things. Thanks Ryan

 

 

Thanks Crawler. I found some Youtube videos with stock vs upgraded turbo's. Unfortunately for my wallet it is stock. Looking into getting a powermax, possibly from Sinister since I already have some blue components😀 Happy New Year
