      ~15HP and ~10 ft-lb. But how it carried the power was a bigger difference. We stopped the pull at 7500rpm, and that was the peak power point (it was almost flat from 7000-7500). With the 4150, the pull peaked around 6900-7000 and started rolling off. (I can't find the exact plots unfortunately or I would post).

      Andrew, I got the car out today and its running so well. The things acts and behaves like a new car. It's always nice to drive a 50 year old car that runs like a 2012 mustang

      Hey i'm all in on the discussion because i'm a potential "victim" of my own engine set up based on what was described. I'm using a Mast 4500 flange intake with Acufab throttle body. I drove it mostly on the track for a year and loved the way it ran but on the street i realized there was no effort in fine tuning it at idle and I realized they just set the idle at 1100rpm. In the test cell a Holley rep was actually there tuning it, here's where i suppose i should've asked more questions. While we were elated with the 750hp pulls i should've also focused on the idle tune. Since then the car has been painted and i'm putting it back together and i'll be "attempting" to figure out the " huge cable throttle body" .....story to be continued.

      Glad to hear you're a fan of DBW when using a larger TB. I have an LS7 being built now, Holley Sniper intake Nick Williams 102mm TB with DBW should make ~700hp at the crank. Custom ground Comp cam, Callies crank, Callies rods, Brian Tooley valve train, custom ported LS3 heads. Went with the NW TB because I've read rave reviews on the product and choose the DBW set up based on my builders recommendation.

Be extra mindful if you have a manual transmission car, because they are especially vulnerable to the negative effects.

      Bump for 2021!!

      I will support all of the other shout-outs for Andrew.
      He got my tune under control, and has everything running great!!
      Five stars!

      I wired everything and did the tuning wizard on the holley.
      It would run, but would not idle below about 1300rpm.
      That is where Andrew picked it up.

      He had a base tune ready and made several tweeks to get it dialed in.
      It only took two sessions to get this thing dialed.
      He explains everything as he goes, and has taught me a lot.
      He was flexible on scheduling on my time and got me in quick.

      Truck starts and idles great, cold or hot.
      Engine is super responsive at all RPMs.
      It pulls like it is going to throw the bed off...LOL

      If anyone is interested, this is my combo...
      1976 Squarebody Truck
      Drivetrain is a 2007 L92 and a 2006 4L80e. (3.40 Ratio Rear)
      I used the Holley Terminator Max Kit 550-928.
      I used the Holley 12-308 fuel module in a new factory tank.
      Factory L92 injectors.

      Modifications are BTR stage 3-V2 truck cam, Circle D 2600-2800 stall, and Speed Engineering 1-7/8" headers.
      It has the factory L92 intake and DBW Throttle Body(87mm), and I have the 10379038 CTSV pedal that Holley recommends.
