I have an 01 7.3 that is for the most part stock. according to my gauge i get about 20 psi of boost. i plan to upgrade my turbo housing and compressor wheel in the future as well as a few other mods. how will this affect my boost? i am wanting a set of new gauges and trying to decide if the 0-30 psi gauge will be enough or if i should get the 0-40. the gauge i have now is 0-60 and it just seems like overkill.
