Injectors Vs Fuel Pressure

[Roadknee]

That does run really strong! My stock 1995 K1500 LO5 will pull 37 to 57 mph in second gear in just over 6 seconds. You're under 4. Wow!

I understand you're running base timing at 0 BTDC in this datalog. So your WOT timing is about 26 degrees. I think your combo could run 32-34 with your heads. Cruising at 2000 rpm and less than 50 MAP you're only running about 28 degrees total. I think your combo could use 40 or more. BLMs are rich in this area already and they'll become richer if you increase the timing so you'll need to reduce the VE tables too. These changes should reduce EGTs.

I think you could add 8-10 base timing for a quick test and go for a cruise to see how it impacts EGTs. Watch knock counts very closely if you're going to lean into the throttle.
