Can you lock up your converter Hemi? If so, you can build boost like a madman with light throttles.

I'm using 1/4" hose. I've emailed drawings and pictures of my EBC to WG plumbing to STS a few times and all is well on that. I have 4.56 gears and a 2600rpm stall converter. The converter has a 2.52 tq multiplier (stator) which really puts down the power off the line. I've got a handscanner that monitors everything on the truck. I might see 1 or 2 degree's timing being pulled out via the pcm.
I installed a Blitz Spec S EBC two weeks ago and got worse results than with the STS EBC.
I think I can put a switch in to lock up my converter but I've never gone about getting the wire diagram for that.

Putfile is working now. Here is the video. This is a 90mph run. Truck weighs 6000# with me in it. If you keep pausing and starting it you'll see the boost #'s exactly and how they go up and drop.

Truck sounds nice!
Those are the exact symptoms I had.
Forgive me here -- I've got a head cold and can't think straight this a.m. -- Doesn't the kit come with 1/8 vac lines?

I just keep wondering if my turbo has enough umph to keep those pipes filled.

What is the A/R size for the hot/exhaust side on the GM kit? The Dodge is 0.96!!!! I wonder if this is why we were having so much trouble building boost in lower gears as the hp/trq values start falling at higher RPM's?

My GT67 was a 0.96 as well.
What size turbo do you guys get? A 67? Do all you guys have trouble with the boost dropping off?
I'm starting to think I had trouble with a 3/8 line, but its been about 18 months lol.
Hemi have you had the WG apart to change springs or anything?

Our base turbo is a T60-1 with a 67 upgrade. I have the T60-1 with a .96 a/r. Almost all of the hemi folks (excluding maybe 1) have had issues with boost in general. The only one I know that has constant solid boost has a Tec 3r standalone system. Comes back around to tq management playing a role???
