Get a vaccuum operated boost guage, show all them ricers how much boost you 'gots at idles, yo'

Dude, you'll have mad fart can yoo' shiznit

 

Sell the trans temp gauge. Your Tahoe is already wired for one and has the sensor. Buy a Denali or HD cluster, plug it in and you have a tranny temp gauge on your dash. Get a fuel pressure gauge with electric sender. Save for the wideband if you're going to go with a turbo/supercharger/Nitrous in the future.

Looks good could you tell me where i can find AIR/fuel ratio, Fuel Pressure, Boost, Gauges that all look the same with the wideband O2 sensor. At a good price. And let me know if i need to look for anything specific for these gauges before i purchase them.

 

Ebay was where I found the best prices. Still not that cheap. You get what you pay for.

When it comes to the wide band, I would recommend calling a sponsor and getting a quote. When youre buying a $400-500 gauge, ebay might not be your best bet.

 

Man I didn't realize they cost that much.
