LS7 inj??

[Chuck L.]

Vehicle is an 07 Escalade.
Am looking at installing the LS7 injs, sold by FAST. [No info available, that I can find on their site. Calling proved to be a waste of time.] The injs are advertised as 39PPH. Shows as pt # 30397. I tracked the part number via a comparo elsewhere, and find that the LS7 inj is listed there also, as 39#. There are additional #'s listed as:
Bosch 0280158051
GM 12576341
The tune that I am looking at in Tune Depot,[06/07 LS7 Vette/E38], shows that inj as being 41.737#. The min pulse shows as .7969, volt mod 1.00.

The ? Which rate is correct?

TIA!

Since the LS7 requires premium fuel, they might use the 41.7 number for flow vs that of inert gas. The 8.1 Marine injectors were often used on the trucks because of the direct fits and flowed 43.82/4 bar, when calculated for regular gas they were 45.13 ppm at 4 bar.

Gordy, thanks for the response! I know the car will run premium only. I'll use the stock Tune Depot values.

They are 42lb injectors. Depends on what the flow was but Bosch flows at 3 bar and GM flows at 4 bar on that injector. If you do the math it is 37 lbs per hour so they must have been showing that.
