There is alot more than just turbo choice here. you need to take everything into account. you need to have the proper tuning setup for every piece in your setup as well as account for weight differences between vehicles. A 200hp vehicle that weighs 2000lbs will probably beat a 500hp duramax that weighs 8000lbs. Do some research and use the search button to finely tune your setup to where you want it.
