I installed a 2005 Tahoe 5.3/4L60E in my 69 suburban. I also installed a used a 1200 Magnacharger, with 17113739 42# injectors and am running a returnless style fuel system. Since I bought the supercharger used, I was not able to get the factory programmer that comes with Magnacharger's new units in order to install their basic tune, but I do have HPTuners. I called Magnacharger directly, but as of yet, they haven't been able to help. If any one has a copy Magnacharger's MP 122 basic tune, to include all the correct fuel injector data I would be greatly appreciative. Please let me know if you have any other questions on my request. Thanks in advance.

They sell the hand held units. I think there SCT now

What format are you looking for HPT or EFILive or some other format?

 

Forgot to mention I have HPTuners so the HPT format would be great! I'm running a returnless style fuel system. TIA

Still looking for the IFR data.

 

Do the injectors have a part number on them? If so that would be a big help.

Nevermind, I am retarded. I skim a lot of threads, missed that.

 

It's in his post.

17113739 - 8.1 marine injectors. Delphi if it makes a difference.

 

Still looking!

 

In the Magnuson tune I found for a return Style 2001, I am Showing 41.6673 across the board.

 

I have injector data. give me your email, and I will forward.

 

Not trying to start anything with anyone but for what it's worth I've used Justin at BBP for my stuff. This had been going on for 4 plus years over different mods that I've done.. Some simple gear changes and some more complex... I've had no problems with him.. The lag in contacting him is frustrating sometimes but he always got back to me. This is a list of what I've done over the years that he tuned for me....
1. Stock Magnuson tvs1900 set up that I installed..
2. This is when BBP starting helping me.. Added 3" pulley from 3.4", ls9 cam and springs, BBP tune, then 90mm throttle body and cold air intake with a BBP tune..
3. ARH 1 7/8 primary headers, id725 injectors, BBP tune.. Then 4.56 gears and correction for that through BBP. Also raised my shift points to 6300 now that I had enough Injector...
4. Left the motor alone and did suspension mods lowered/traction bars heavy tie rods etc.
Next will be a shift kit and pt2800 stall converter, 8 rib pulley kit with overdrive crank pulley and I'll have him tune it again.... No issues with anything. Hope this helps.
Truck is a 2004 2500 4x4 6.0.
