I'm adding over the winter gt40 heads upgraded springs and trickflow stage 1 camshaft. I already have professional products upper amd lower 70mm throttle body lightning maf Cai electric fans t5 373. Should I add 24
24lbs injectors? My car is already dyno tuned with a chip. Made 251hp 295 torq to the wheels. What do you think ill see after the heads and cam upgrade?

I had a similar setup and went with 24 lb. After doing the math, I figured I was stretching the stock 19lb a little too high into their duty cycle. I think, technically, they would have been fine. But they were probably not working at their full capacity due to age, wear, dirt, etc. So I wanted to replace them anyway. Going with 24lb was some added security. You definitely don't want to go lean at 6k rpm.
