yes, i used LS3 style injectors from FAST!

 

I getting ready to install mine on my 82 wagon. There are all kinds of lines going into the current l92 intake. What did you do on the back of the intake where you pulled vaccum from the intake. I'm a little confused on that. The map goes into the top of the intake and how did you handle that

 

I ran a hosr from the fitting to the map sensor elsewhere. I have a brick style map thought. Used the big fitting to run a hose to a vacuum block for everything else.

 

HuH? Not sure what you mean

 

Richard, do you have a link or a pic to what MAP you are using?

 

Its the one that came with my alky control kit actually...like this one MAP - GM 3 Bar MAP Sensor DIYAutoTune.com

 

Do those MAP's come with offset data and everything for a gen III OS?

 

You can find it online...i actually just measured mine with a voltmeter to make it.

 

I got a question for you guys using the Holley Hi-ram intakes. I have a 2009 Sierra Denali with the 6.2L (L92) motor. It's currently has a Texas Speed VVT camshaft package, LS3 Ported cylinder heads, 1 7/8" Longtubes and CAI. I am contemplating buying the Holley Hi-Ram for it and the Nick Williams 102mm drive by wire TB, for N/A for awhile. In the future I am going to FI my truck, and I want to know which setup would make more power in your opinion. Taking off the Hi-ram and installing a whipple in its place or leaving the Hi-ram and bolting on a Procharger and tubing it into the Hi-Ram? Curious to hear some opinions.

Thanks

 

So your question is what makes more power a whipple or procharger? Depends on what size whipple and what size procharger.
