Hello all, been cruising through the forums for a while.
Bought my 2011 CTS-V 6 months ago or so.
Little info, I live in Ontario Canada. I have no E85 close by me. I also don’t have any reputable engine places near me to steer me in the right directions.
Car currently puts down 673hp 662t with the belt slipping and not making full boost. The mods will be in an attached picture.
I have a ProMeth kit waiting to be installed, and I have a Kong 2650 with 3” pulley in the mail.
My few questions are as I’ve read many different things on fuel.
Where do my stock pumps run out? Do I need new pumps, or can I up the voltage?

I know my crank is forged, but how good is it?I know I need to put forged pistons in, but should I do the rods and crank while I’m in there?

anythung else I should know before or after we instal the meth,bigger blower and tune it?

You're going to need to address the fuel system with the Kong 2650. If sticking to pump gas, the DSX auxiliary fuel pump kit would support your goals.

For the bottom end, depending on the end goal, a set of rods and pistons with the factory crank is a great option to add some additional headroom.

Let us know if we can help.

You didn't mention where in Ontario you live, but I can recommend 20Twenty Speed in Dundas for tuning.

Is it a preference thing on upgrading the intank pumps vs running the DSX aux pump kit and if doing the intank pump upgrade do you recommend the AEM or DW I mean I know u sell both but I’m only trying to crack open that tank and tear apart that fuel pump unit once

I would like to know that as well.
I’ve also read somewhere you can just tune the FCIM to put out more voltage?

The DSX aux pump seems like a lot of messing around. Would a set of the AEM pumps or DW pumps work that are listed on your site? Or is the DSX way better than those pumps?

If you want to run the Kong 2650, you will need:

1. ALM stage two fuel pump hat (@adam112)
- you won't have to drill the tank and this replaces the inevitable leaking plastic elbow, as well as increases flow

2. DW300 in-tank pumps. Your stockers are getting old and friends don't let friends buy AEM.

3. Either a Dsteck kit (plumbed to the fuel hat, not the tank) or a Vaporworx ally controller and you upgrade the fuel lines like I did.

4. Either fuel rails or modify the factory rails to fit the Kong 2650.

I personally just wound up running entirely new fuel line- once you get fuel rails for the Kong and an ALM hat, it makes sense just to bypass the factory metal lines. Once you do that, for the Aux kit it's just a matter of plumbing in the pump and hooking up your controller of choice.

I have a few threads here on that and the Vaporworx fuel controllers. My Opulent thread in the build section covers a lot of it, plus the fuel section.

It's not cheap, but neither is that 2650. !D
