doesnt the tahoe have hydraboost? if it does then boost is multiplied by the use of the power steering pump not vacuum and the master cylinder should sit on this fixture that has i think two steel lines running out of it and into yoru p.s system"i dont think you got the picture. i got a beautiful picture. this baby happens to have an extra turn of speed, which is the only thing i care about. you dont understnad what happens do you? they make cars. they make 'em exactly the same way. one or two of 'em turn out to be something special. nobody knows why. i know why. i may be kiddin' myself, but i think i can make somethin' out of that sad little bucket of bolts." ~ Tennessee Steinmetz

when adding the seafoam to the fuel, does it matter on what level the tank is at? should i run it empty then put the seafoam in a the gas station and and fill 'er back up? or is there no preference?

the more fuel in the tank the longer you'll be running it thru, so in my opinion 1/2 -2/2 is better than emptier cus it will be cleaning more and longer and if you put it in at a lower level you might get a rough idle for a while cus it doesnt burn off as good as gas03 Silverado 1500

Add a can to the crankcase and a can to the gas tank at the same time, planning for an oil change. I say this since I would change the engine oil after about 200-300 miles (i.e. about a tank of gas). Don't run SF in the crankcase any longer since it will cause the oil to start to deteriorate as it works over the sludge and gunk in the engine. I will plan in an oil change and SF the top end (thru the vacuum line) and the TB in the same service. One tip that's worked well for me is to SF the top end and TB, drive it after letting it sit to clear out the crap and then do the oil change. That way everything is all cleaned up and then you change out the oil- good as new!
Change out the oil and filter and drive the hell out of it!

Sea Foam in newer vehicles...
So what about newer vehicles? Is this a good thing to run about every 2-3 oil changes? Maybe just for preventive maintenance...? Perhaps not the oil until about 35-40k but as far as fuel goes.. I would feel maybe a can in the fuel tank every 2-3 oil changes wouldnt hurt anybody... Ideas? Opinions?GO GATORS!!!

Actually, I have been using SF in newer vehicles specifically in the gas tank. Since newer vehicles tend to have the filter in the tank (not owner replaceable) I have been using it to keep the tank and fuel system cleaned out. I'll add a can about once every 6 months and have never had a fuel related problem in the cars or bikes.
As for the crankcase, I will use it about once a year just for good measure generally in the fall.

Murdog94 - When you say pour SF in the brake booster line at 1200 to 1500 rpm and then let sit, do you mean let it sit for an hour to 2 hours whiles its running or shut off?
