Work in progress ?

 

[Yukon Bush Tremor]

Thanks man! Should be super helpful and valuable once completed!

I would like to say thank you but I think you just cost me a lot of money. I made the mistake of looking at the Forced Induction links. Oh baby!

Pro Charger looks sweet and simple. I'm afraid to see if it has all the necessary CARB numbers for the communist state I reside in.

You can add to tuners: Livernois Motorsports. They have really good vid on their 7.3 tune on YouTube
Palm Beach Dyno also has a tune that I've heard good things about.

5 Star Tunes too

Do Pedal tuners count? There’s a few of those out there.

I think I'm going to be getting into some trouble.

 

[mothra]

I want!!!

Great list and good to see I've checked a few boxes on @driftwoodsvt list. Cold air intake, headers, mid-pipe and cat back system are all AFE. I went back and forth on the tuner between AFE and 5Star. Based on my research, I went 5Star and although I've not installed it yet, the results posted on this site by others that have installed it make me happy with my decision.

I'll be getting everything installed as soon as the backordered parts from AFE arrive.

What type of hp/tq do longtubes make on the 7.3?

As a rule of thumb, headers are good for 25-35 HP. I saw a test on a 7.3 and want to say it may have been in the 30+ range but honestly don't recall. There's so many different builders trying things right now. Someone has gotten 1k hp N/A now on a stock bottom end.

25-35 wheel or crank?

Stainless Works now has a true dual setup as well as headers specifically for the 7.3.

Which is super expensive. I did my true dual at about 40% of there costs.

So was my Tremor ?

It's less than the complete AFE system I ordered.
