Suburban update and a couple ??s

[chevmasta]

Well, since we have your attention, chevmaster, thank you for the tuned, smoothed, stock 454 file for comparison. Take a look at what a roller cam and going up nearly 2 points in compression does to the fueling. Stock 454 VE in blue, cammed/compression 454 in black. Keep in mind, mine isn't complete, yet, but it's pretty close from 0-50mph driving the truck normally. Next up is to replace the partially fouled throw away bosch plugs with good ACDelcos, do the first oil change, then some more tuning.

Question,
What is your fuel pressure set at?
what is your BPC set at?

As you can see in MY VE map, I need to raise BPC and re-tune my VE table to lower the values in the maxxed out VE up top.

Don't forget to share your spark table!
