I want to get some gauges for my '04 truck with the HO engine. The engine is completely stock and I plan on keeping it that way (at least for the foreseeable future). Is a 30 PSI boost gauge big enough or should I get a higher PSI one? I don't know how much boost the turbo can put out on a stock truck.

Thanks in advance.

 

I would get a 60 just in case,you never know what you'll want in the future and I don't think it's really any more money.
