Will upgrading injectors on a bone stock LS1 make any difference?
I am assuming that HP Tuners is correct. Yes. Otherwise I would have to tape someone under the hood and measure it with a real time DVOM and then do quite a few calculations with the wind blowing at his face.
AFR tells the story not the "cheap" scan tools we use. If the AFR is OK the engine is OK for NA atleast. Guys with "faster than they should be" cars tend to agree with trying to max out injectors for best ET. More folks should listen to those guys rather than the people who just spend mountains of cash.
I can also use a fuel pressure gauge to watch the pressure drop at WOT on quite a few cars. That means you go back in and skew the PE/MAP/VE table to meet your afr and ask for more duty cycle on your injectors. Seems legit.
The AFR will also lose resolution at the end of the tail pipe where nearly all dynos are set up to pull the reading from. Yes there are a few guys that weld in the bung or have the extra bung in the header do to that with, but not as many as use the tail pipe sniffer.
If you set the AFR and the DC is 101% you dont see a problem with that, then I see a problem with your reasoning. Tell me how a 5k snap on/otc scanner is cheap also.
