I am wanting to purchase a Holley 105MM Hi-Ram instake for my 2009 GMC Sierra Denali with the 6.2L (L92) with the Holley 105MM DBW throttle body. I am wanting to know if anyone has any experience with the conversion from DBW to DBC and what all it needs to be done to make the conversion happen.

Thanks

 

I do not think it is even possible if you are trying to stay with the factory computer.

Do you plan on going turbo or something???

If not, that intake would be a wrong investment, you'd wish you didn't buy it.

You'll still be able to make great power with the stock throttle body and it's been proven. It'll make power that won't even be useable on the streets because you'll be blowing the tires off all the time.

 

The truck has a Texas speed VVT camshaft package, LS3 ported heads, 1 7/8" long tubes, circle D 2800 stall. I am wanting to run the Holley Hi-ram intake with a procharger tubed into the Holley hi-ram. Nick Williams makes a 102mm that's drive by wire. Just seeing my options on drive by cable
